What Is the Definition of Effervescence in Chemistry

Effervescence is foaming or fizzing that results from a gas being evolved from a solid or liquid. The term comes from the Latin verb fervere, which means to boil. The word fermentation has the same source. The most common gas released in effervescence is carbon dioxide, however nitrogen gas may be dissolved in liquids to produce smaller bubbles. Examples of Effervescence Common examples of effervescence include bubbles and foam from champagne, carbonated soft drinks, and beer. It may be observed in the reaction between hydrochloric acid and limestone or between HCl and an antacid table. Sources Baxter, E. Denise; Hughes, Paul S. (2001).

Female Characters In Candide Essay Example For Students

Female Characters In Candide Essay Francois Marie Arouet de Voltaires novella, Candide, incorporates many themes, yet concentrates a direct assault on the ideas of Leibniz and Pope. These two well-known philosophers both held the viewpoint that the world created by God was the best of all possibilities, a world of perfect order and reason. Pope specifically felt that each human being is a part of Gods great and all knowing plan or design for the world. Voltaire had a very opposite point of view in that he saw a world of needless pain and suffering all around him. Voltaire, a deist, believed that God created the world, yet he felt that the people were living in a situation that was anything but perfect. Thus, the major theme of Candide is one of the world not being the best of all possibilities, full of actions definitely not determined by reason or order, but by chance and coincidence. To prove his point, Voltaire uses pointed satire directed at various organizations and groups prevalent in his time period. In particular, Voltaire takes aim at organized religion, in particular Catholicism, as well as aristocratic arrogance and war. All of Voltaires comments are precisely chosen to convey his point that those in power were completely corrupt in all their thoughts and actions. Throughout the entire book, Voltaire portrays religious men, such as monks and priests, as hypocrites who do not live up to the religious standards that they set upon others. Voltaire first attacks the men of the Church and their hypocrisy in chapter three. After escaping from the Bulgars, Candide was obviously in need of food and possibly medical attention, but could find no help. When he came upon a minister who had just spoken of charity, Candide asked for some food to eat, but was harshly turned away. After speaking of charity to others, the minister turned Candide away just because they didnt share the same view of the Pope. To make matters worse, the ministers wife proceeded to throw a pot of urine over Candides head. Voltaire used these rather repulsive acts to show the hypocrisy found in many church affiliated men of his time. One minute the minister was talking to the townspeople of charity and brotherly love, while the next minute he rudely dismissed a man in need of that v ery Christian ideal. While I dont completely agree with Voltaire that the religious men of that time were so blatantly hypocritical, I do feel that they were a bit confused. They were so content on teaching others by words and not actions. In many situations, it is the actions that make the impactnot the words. Voltaire saw the ministers speak of brotherly with their mouths, but turn their back on those who needed the guidance and love of which they preached. Voltaire elaborated further on brotherly love by introducing the character of James, the Anabaptist. James is described as, A man who had never been christeneda creature without wings but with two legs and a soul. (27). This very man took Candide in with an offering of bread, drink, money, and the opportunity to learn a trade. James was the exact opposite of the minister in more ways than just his kind actions towards Candide. The description of James said that he was not an angel, but he did have a soul. By using this severe character contrast, Voltaire is saying that those who may not hold high positions of power in the Church, many times show more Christian love than those who do. I agree with Voltaire in that many times people look to those in authority to find guidance, when in reality, they can find true love and fellowship right in their midst. During the Enlightenment, officials in the Church were not the same people who truly touched the hearts and lives of the people around them. Beyond attacking men of faith, Voltaire depicts the Church as oppressive, corrupt, and he felt that it was of no need to the general public. In chapter six, Pangloss is hanged for his speech and Candide simply for listening with an air of approbation The reason given for this hanging is that the people believed a ritual hanging would keep the

Women Have Come A Long Way Essay Example For Students

Women Have Come A Long Way Essay Women have been an inspiration for many writers for centuries. They have been celebrated as symbols of beauty, affection and strength, and we usually connect them with motherhood and raising children. The works about women very often reveal not only lives of women, but they also describe the times and problems they had to face, and they provide a very clear picture about the whole society of the times when these works were created. Contrasting the modern day women to the women in Voltaire’s period we can look into the past and the present and see how women’s roles have changed. After centuries of conforming to female stereotypes created by men, women are slowly taking control of their own image making. Image of being equal to the men and being able to face the reality of life on their own, without men’s support. We will write a custom essay on Women Have Come A Long Way specifically for you for only $16.38 $13.9/page Order now In the past the traditional concepts of what it means to be a woman were taught in the early stages of development. Parents encourage outdated roles in the way little girls are dressed, the toys they play with, and the books that are read to them. As pointed out in â€Å"X: A Fabulous Child’s Story† by Lois Gould, girls were treated a distinct way. In the late 1800s, women did not play an important role in society at all. Their job was mainly to cook, clean, sew, take care of the children, and keep the house in order. They were treated as a material possession rather than a human being that could think and act for themselves and looked upon as a decorative member of the household. Women were treated just as sex objects , alive just to satisfy a mans needs and desires. They were robbed of their true identity. The male always dominated over the women and it was not viewed as â€Å"unfair.† The history of mankind is a history of repeated injuries on the part of men toward woman, having in direct object the establishment of an absolute tyranny over her.† (Declaration of Sentiments) It was believed that women were the inferior gender and had to have special attention given to them. Women were also very limited in their rights in 1872. Such rights included: women had to submit to laws when they had no voice in their formation, married women had no property rights, husbands had legal power over and responsibility for their wives to the extent that they could imprison or beat them with impunity, divorce and child custody laws favored men, giving no rights to women and when women did work they were paid only a fraction of what men earned, women were not allowed to enter professions such as medicine or law, and women were robbed of their self-confidence and self-respect, and were made totally dependent on men. (Declaration of Sentiments)But times have changed now. Women now have the power to do anything they want to when they put their minds to it. Over the last century women have made incredible progress in their struggle to claim their equal rights and humanity, gaining the right to vote in 1920 under the 19th amendment in the constitution, gaining a right to an equal education, owning property and having a job. Women’s new role in society is focused on independence. Society has found that women are able to succeed without set limitations and expectations despite earlier notions. The media no longer focuses primarily on superficial aspects of women but also on a more profound basis. In Ever After, a modern version of Cinderella, Danielle is respected not only for her beauty but also for her intelligence and distinct personality. She shares her knowledge of democracy, education, and equality with Henry, the prince. Danielle’s actions represent the new forms of empowerment modern women strive for.Women are now encouraged to educate themselves beyond the domestic elements. Advertisements share this idea of a  "new woman.† Hamburger Helper ads typically present workingwomen who are also able to make dinner for the family. In â€Å"Beauty and the Beast of Advertising,† Jean Kilbourne recognizes that it is somewhat common to see a â€Å"liberated woman† with â€Å"independence and self-esteem†. Similar ideas of independence are portrayed in the business world. New positions are shaped for strong-willed women who are able to take on more responsibility. These new roles for women are continuing to gain acceptance. The play â€Å"Antigone† is built on the conflicts between man and women and their roles in society. Creon is an authoritative figure who feels his authority should not be undermined by anyone, especially a woman (Antigone). Antigone with her strong belief that all the dead deserves honor buries her brother Polynices which was a strict violation of the king’s law. This act of Antigone was very courageous. Creon never allowed any man to go aga inst him and definitely no woman. He believed that until he is alive no woman is going to lord over him. Even in such a situation where Antigone’s life depends on it she calmly and eloquently argues the righteousness of her actions instead of quivering with fear under Creon’s threats. This small paragraph from the play proves that men cannot suppress women and they can challenge men in every field. .u4e6aa2470cebab67fb797307c32e47e8 , .u4e6aa2470cebab67fb797307c32e47e8 .postImageUrl , .u4e6aa2470cebab67fb797307c32e47e8 .centered-text-area { min-height: 80px; position: relative; } .u4e6aa2470cebab67fb797307c32e47e8 , .u4e6aa2470cebab67fb797307c32e47e8:hover , .u4e6aa2470cebab67fb797307c32e47e8:visited , .u4e6aa2470cebab67fb797307c32e47e8:active { border:0!important; } .u4e6aa2470cebab67fb797307c32e47e8 .clearfix:after { content: ""; display: table; clear: both; } .u4e6aa2470cebab67fb797307c32e47e8 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u4e6aa2470cebab67fb797307c32e47e8:active , .u4e6aa2470cebab67fb797307c32e47e8:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u4e6aa2470cebab67fb797307c32e47e8 .centered-text-area { width: 100%; position: relative ; } .u4e6aa2470cebab67fb797307c32e47e8 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u4e6aa2470cebab67fb797307c32e47e8 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u4e6aa2470cebab67fb797307c32e47e8 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u4e6aa2470cebab67fb797307c32e47e8:hover .ctaButton { background-color: #34495E!important; } .u4e6aa2470cebab67fb797307c32e47e8 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u4e6aa2470cebab67fb797307c32e47e8 .u4e6aa2470cebab67fb797307c32e47e8-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u4e6aa2470cebab67fb797307c32e47e8:after { content: ""; display: block; clear: both; } READ: Aristotle on Rhetoric EssayWomen have improved their ability to succeed in life and realized that they are not just sex objects but people who have the same right as men. Women have made an incredible appearance and play an immense role in today’s society. Women are basically treated with equality today with men and the times sure have changed. In modern day society, women are very well educated and have improved in many areas. Being educated they learned that they can succeed in the working force and use laws that protect them from being discriminated against in any situation. Nonetheless in some households women are treated with no respect. They are sometimes told what to do. The only difference today is that women have their own opinions and can speak their minds. Women have become independent and they do not need men to support them. Bibliography:
