Charles, Jacques-Alexandre-Cesar

Charles, Jacques Alexandre Cesar (1746-1823) French inventor, scientist, mathematician and balloonist. 

Charles, Jacques-Alexandre-Cesar (1746-1823) French physicist and physical chemist who, with Joseph-Louis Gay-Lussac, established a law of the changes in gas volume caused by temperature changes at constant pressure. This is commonly known as Charles law of pressures. 

Charles, Jacques Alexandre Cesar (1746-1823) A French chemist and physicist best known for his discovery of Charles s law. He made the first hydrogen balloon ascent in 1783, which was sponsored by the Academic des Sciences. He prepared the hydrogen, filled the balloon, and with an assistant, Nicolas-Louis Robert (1760-1820), rose to aheight of over 500 m. He also experimented with atmospheric electricity. 

Boyle also observed that heating a gas causes it to expand in volume, but more than a century passed before Jacques-Alexandre-Cesar Charles reported the first quantitative studies of gas volume as a function of temperature. Charles found that for a fixed amount of gas, a graph of gas volume vs. temperature gives a straight line, as shown in Figure 5. In other words, the volume of a gas is directly proportional to its temperature ... 

Jacques Alexandre Cesar Charles was born in France in 1746. He was a scientist who developed many inventions. He is especially remembered for something he did on August 27,1783. That day, Charles launched an enormous balloon that was made of silk that had been coated with varnish. The balloon was filled with hydrogen gas. When the ropes holding the floating balloon were cut, it slowly ascended (rose) into the air. The balloon reached almost 3,000 feet (914 meters) before it landed just outside Paris, France. 

Jacques-Alexandre-Cesar Charles was a mathematician and physicist remembered for his pioneering work with gases and hydrogen balloon flights. Charles was born on November 12, 1746, in Beaugency, Loiret, France his first occupation was as a clerk at the Ministry of Finance in Paris. However, his interests eventually turned to science. 

It is called after Jacques Alexandre Cesar Charles... 

Charles volume law is sometimes called Gay-Lussac s law after its independent discoverer. The law is named for both the French physicist and physical chemist Jacques Alexandre Cesar Charles (1746-1823) and for the French physicist Joseph-Louis Gay-Lussac (1778-1850). See also absolute temperature gas laws. 

Jacques Alexandre Cesar Charles (1746-1823). French physicist. He was a gifted lecturer, an inventor of scientific apparatus, and the first person to use hydrogen to inflate balloons. 

Jacques Alexandre Cesar Charles (1746-1823) was a French scientist who was interested in both the behavior of gases and the behavior of balloons, the latter of which were just being developed when Charles was in his early thirties. 

Jacques-Alexandre-Cesar Charles to try to duplicate this phenomenon. As a result Charles observed that the volume of a gas is directly proportional to its temperature.
