Mary Wollstonecraft and Mary Shelley

Mary Wollstonecraft and Mary Shelley Mary Wollstonecraft was a pioneer in feminist thinking and writing. The author gave birth to Mary Wollstonecraft Shelley in 1797. Wollstonecraft died soon after childbirth due to a fever. How could this have influenced Shelley’s writings? Although her mother did not live long enough to influence Shelley directly, it is clear that the Wollstonecraft and the ideas of the Romantic era greatly shaped Shelley’s beliefs. The Life of Mary Wollstonecraft Wollstonecraft was strongly influenced by Thomas Paine and argued that women deserved equal rights. She saw how her own father treated her mother as property and refused to allow the same future for herself. When she became old enough, she earned a living as a governess but was bored with this work. She wanted to challenge her high intellect. When she was 28, she wrote a semi-autobiographical novel titled Maria. She soon moved to London and became an admired professional writer and editor who wrote about the rights of women and children. In 1790, Wollstonecraft wrote her essay A Vindication of the Rights of Men based on her reaction to the French Revolution. This essay influenced her famous feminist social study A Vindication of the Rights of Woman, which she wrote two years later. The work continues to be read in literature and Womens studies classes today. Wollstonecraft experienced two romantic affairs and gave birth to Fanny before falling in love with William Godwin. By November  1796, she became pregnant with their only child, Mary Wollstonecraft Shelley. Godwin and she were married in March of the following year. During the summer, she began writing The Wrongs of Women: or Maria. Shelley was born on August 30 and Wollstonecraft died less than two weeks later. Godwin raised both Fanny and Mary surrounded by philosophers and poets, such as Coleridge and Lamb. He also taught Mary to read and spell her name by having her trace her mothers inscription on the stone. Mary Shelley and Frankenstein With much of the independent spirit that drove her mother, Mary left home when she was 16 to live with her lover, Percy Shelley, who was unhappily married at the time. Society and even her father treated her as an outcast. This rejection influenced her writings greatly. Along with the suicides of Percys estranged wife and then Marys half-sister Fanny, her alienated status inspired her to write her greatest work, Frankenstein. Frankenstein is often referenced as the start of Science Fiction. Legend  claims that Shelley wrote the whole book in one night as part of a competition between herself, Percy Shelley, Lord Byron and John Polidori. The aim was to see who could write the best horror story. While Shelleys tale isnt usually classified as a horror it did spawn a new genre mixing moral questions with science.

Boiling Definition in Chemistry

Boiling Definition in Chemistry Boiling is defined as  a phase transition from the liquid state to the gas state, usually occurring when a liquid is heated to its boiling point. At the boiling point, the vapor pressure of the liquid is the same as the external pressure acting upon its surface. Also Known As:  Two other words for boiling are  ebullition and vaporization. Boiling Example A good example of boiling is seen when water is heated until it forms steam. The boiling point of  fresh water at sea level  is  212 °F (100 °C).  The bubbles that form in the water contain the vapor phase of water, which is steam. The bubbles expand as they get closer to the surface because there is less pressure acting upon them. Boiling Versus Evaporation In the process of evaporation, particles may transition from the liquid phase to the gas phase. However, boiling and evaporation do not mean the same thing. Boiling occurs throughout the volume of a liquid, while evaporation only occurs at the surface interface between the liquid and its surroundings. The bubbles that form during boiling do not form during evaporation. In evaporation, the liquid molecules have different kinetic energy values from one another.
