The purpose of this lab was to determine the effect of temperature on the volume of gas when the pressure is consistent and to verify Charles’ Law. The data from the experiment reveals that as temperature increases, so does volume. This also indicates that as temperature decreases, the volume decreases as well.…

The three gas laws include: Gay-Lussac’s law, Boyle’s law and Charles’ law. When combined with Avogadro’s law the three laws can be generalized by the ideal gas law. Gases possess observable properties which include, mass, pressure (P), thermodynamic temperature (T) and volume (V). These properties are related to each other and the state of a gas is determined by their values. The three laws are derived from these properties.…

But element 85 gives our study a greater depth than has yet been revealed by the already covered elements. What this story shows is that the nationalistic prejudices persist to this day in many respects and that the identity of the “discoverer” of the element very much depends on the nationality of the textbook that one might consult. It is also an element for which the majority of sources give an incorrect account in declaring Corson, MacKenzie, and Segrè as the true discoverers. The account I will detail owes much to the recent work of two young chemists, Brett Thornton and Shawn Burdette, whose 2010 article I have drawn heavily from.…

He created the reflecting goniometer, improved the Gravesand heliostat, and Fahrenheit’s aerometer (“Jacques” Britannica). His works with ballooning lead to his discovery that the volume of a gas is a direct function of its temperature (“Jacques” Physics). He called this Charles law and it is considered the second fundamental property of gasses (Schueller). He never published his works but later his student found the same thing, published it, and gave him the…

Avogadro proposed, correctly, that any gas in a container of the same size, with the same temperature and pressure, would have roughly the same number of molecules in it, no matter what the gas was. So any difference in mass between two flasks of the same size full of two different gases would be because of a difference in the actual physical mass of the molecules. And thus, Avogadro basically figured…

His laws and inventions have been applied to modern science. The Gay-Lussac gas law can be applied to many everyday norms. This ranges from the use of a pressure cooker, to the use of hot-air balloons. When using a pressure cooker, the mass and contents inside (including the air and vapor) are constant. Since pressure and temperature are directly proportionate, an increase in temperature will result in an increase in pressure. His invention of the alcohol-by-volume has benefited the global beer and winery industry. Companies can now monitor the processing of beer and wine products with respect to alcohol-content. The alcohol-by-volume standard measurement has enabled the governments all over the world to classify alcoholic beverages according to their ABV percentage, and also establish laws that control the processing of these beverages and heir distribution. Nowadays, we have adequate information on the effects of temperature, pressure, and volume on gases. His constant use of hot-air balloons led to their use in spying during World War I. In our modern times, hot-air ballooning has turned out to be a sport and enjoyable activity. Hot-air balloons are also used to collect atmospheric data, and for observing the migration of birds. Gay-Lussac has immensely contributed to the chemistry knowledge and has inspired the continued research in chemistry as well as the discovery and inventions of new processes, laws, and…

It took many scientists and philosophers hundreds even thousands of years to come up with an accurate atomic theory. For nearly 2,000 years science was unable to come up with experiments that were able to test and put forth the theories made up by Democritus which was a fifth century B.C. Greek philosopher. In 1803, John Dalton, who viewed the atom as a small solid sphere, and is credited for the developing of the first coherent atomic theory was now in the picture. This all led to the the first periodic table of the elements, and the history of the atom.…

Hearing early in 1609 that a Dutch optician, named Lippershey, had produced an instrument by which the apparent size of remote objects was magnified, Galileo at once realized the principle by which such a result could alone be achieved, and, after a single night devoted to consideration of the laws of refraction, he succeeded in constructing a telescope which magnified three times, its magnifying power being soon increased to thirty-two.…

Chlorine is an element I would like to present today. It is discovered in 1774 by Carl Wilhelm Scheele and was named by Sir Humphry Davy in 1810, after a Greek word, khlôros, which means greenish yellow. Chlorine is in the halogen group in the periodic table with an atomic number of seventeen. Pure chlorine is yellowish-green but most common compounds with chlorine are typically colourless.…
