It is not surprising that he made important contributions to biology and to paleontology. Relatively little is known about Robert Hooke's life. He was born on July 18, 1635, at Freshwater, on the Isle of Wight, the son of a churchman. He was apparently educated at home by his father, although he also served an apprenticeship to an artist. He was able to enter Westminster School at the age of thirteen, and from there went to Oxford, where some of the best scientists in England were working at the time.
The first time she began to adore astronomy was when she helped her father built a small observatory. She had many things going for her like becoming a librarian, working with her father at a bank but, science was the one thing she enjoyed and wanted to pursue the most. Marie Mitchell was born and raised in Nantucket, Massachusetts on August 1st, 1887 and died June 28th, 1889. She was raised by her Quaker parents William Mitchell and Lydia Coleman. Her parents highly valued education and wanted her to receive the same education that boys receive.
Lesson 13.6 Changes of physical state: * necessary to draw a temperature-energy graph to see the change in temperature with a constant application of heat Heat of fusion - the amount of heat required to melt 1.00 g of substance. substance changing from a solid to a liquid. Heat of vaporization - the amount of heat required to vaporize 1.00 g of a substance. substance changing from a liquid to a gas. heats of vaporization and condensation are equal.
The melting point of paradichlorobenzine is approximately 53.5 °C but my graph illustrates it at 51°C. ( (Note this is due to the different atmospheric pressures and concentration of paradichlorobenzine which causes some minor variation.) 5. I can conclude that both the melting and boiling points of a pure substance are the (almost) the same. This is due to the fact that pure substances (unlike mixtures) have definite composition.
Afsana Islam CHEM 106 – LAB Lab Report #4 03/02/2015 Focus Questions: Is mass conserved in the chemical reaction that you studied in lab? The mass of the zinc and iodine were definitely conserved. The mass did not change much after the chemical reaction occurred. Raw Data: Experiment # Mass of “R” boiling tube Mass of Zinc used in Mass of Iodine used in Mass of excess zinc and “R” boiling tube after r/h/c Mass of excess zinc and “R” boiling tube after r/h/c a 2nd time Mass of “P” boiling tube and boiling chip Mass of “P” boiling tube, boiling chip, and zinc iodide after h/c Mass of “P” boiling tube, boiling chip, and zinc iodide after h/c a 2nd time 1 40.63g 2.00g 3.00g 40.83g 40.83g 41.46g 45.29g 45.29g 2 40.63g 1.00g 2.00g 41.09g 41.09g 42.25g 44.60g 44.60g
Heat-Capacity Ratios for Gases Abstract A Kundt’s tube was used to find the speed of sound in various gases at 190C, leading to the determination of the heat-capacity ratios for the gases with a 95% confidence interval. The gases used in the experiment were air, argon, carbon dioxide, helium, nitrogen, and oxygen. The average speed of sound for air was obtained to be 329 ± 17.6 m/s, argon 318 ± .325 m/s, carbon dioxide 266 ± .870 m/s, helium 999 ± 2.11 m/s, nitrogen 348 ± .253 m/s, oxygen 325 ± .130 m/s. These values are very close to the accepted values for the speed of sound in these gases as explained in the Results section. As a result of such accurate laboratory determinations most of the heat-capacity ratios have a small percent error.
Maxwell began his undergraduate studies at Edinburgh University at age sixteen and entered graduate school at Cambridge University at age nineteen. After graduation, he was a fellow and professor at a variety of colleges in the United Kingdom. Maxwell was inducted as a Fellow of The Royal Society of Edinburgh when he was 25, and promoted to a Fellow of The Royal Society at age 30. After a fruitful career, James Maxwell passed away at the age of 48 of stomach cancer, which was oddly the same cause and timing of his mother’s death when Maxwell was eight years old (Forfar, 1995). Before we start talking about Maxwell’s Equations, let’s look back into history.
Pascal decided to learn about geometry, a topic he had only heard of but never studied, in his spare time. By age thirteen, he had proven the 32nd proposition of Euclid and discovered an error in Rene Descartes geometry. His father put Pascal’s knowledge in mathematics towards hand totaling long columns of numbers to his job. Pascal later went on the create the pascaline, a device fourteen by five by three inches that could do calculations, which can now be considered the first mechanical calculator. In 1650, Pascal suddenly decided to avidly study religion, but returned to his previous lifestyle three years later, conducting experiments on the pressure exerted by gases and liquids, inventing the arithmetical triangle, and created the calculus of probabilities together with Fermat.
Einstein was a physicist, He resided at many countries namely: Germany, Belgium, Italy, Switzerland, Hungary, and The United States of America. He has obtained citizenship in most of the places he resided. He has won some notable awards including a nobel prize in 1921 for his contribution in the field of physics. He acquired interest in science and mathematics at a very young age, When his father gave him a compass and he observed something made the needles move and he began experimenting on how it works. His father Herman Einstein was an Engineer while his mother was called Pauline Einstein.
For a gas, the Heat capacity depends on how one does the heating. The Heat Capacity at constant Volume, CV, and the Heat Capacity at constant pressure, Cp, for any given substance are are almost exactly equal if the substance is a solid or a liquid. This means that for a liquid or a solid, the heat capacity doesn't depend on how you perform the heating. Cp and CV are not equal for a gas; Cp is always greater than CV by a constant value. For one mole of gas, the difference between Cp and CV is the constant R (R is the so called universal gas constant) and represents the capacity of the gas to perform expansion work at constant applied pressure.
