Jacques Charles Totally Explained

Everything about Jacques Alexandre C Sar Charles totally explained

Jacques Alexandre César Charles (November 12, 1746 – April 7, 1823) was a French inventor, scientist, mathematician, and balloonist.
Charles was born in Beaugency-sur-Loire, and made the first flight of a hydrogen balloon on August 27 1783.This balloon was destroyed by terrified peasants when it landed outside of Paris. On December 1 1783, a mere ten days after the manned flight of the Montgolfier hot-air balloon, Charles with Ainé Roberts, ascended to a height of about 1,800 feet (550 meters) in his balloon "La Charlière". Montgolfier's principal scientific collaborator was M. Charles, ... who had been the first to propose the gas produced by vitriol instead of the burning, dampened straw and wood that he'd used in earlier flights. Charles himself was also eager to ascend but had run into a firm veto from the King, who from the earliest reports had been observing the progress of the flights with keen attentiveness. Anxious about the perils of a maiden flight, the King had then proposed that two criminals be sent up in a basket, at which Charles and his colleagues became indignant.

Inventions

He developed several useful inventions, including a valve to let hydrogen out of the balloon and other devices, such as the hydrometer and reflecting goniometer, and improved the Gravesand heliostat and Fahrenheit's aerometer. In addition he confirmed Benjamin Franklin's electrical experiments. Around 1787 he discovered Charles' Law, which states that under constant pressure, an ideal gas' volume is proportional to its absolute temperature. The volume of a gas at constant pressure increases linearly with the absolute temperature of the gas. The formula he created was V₁/T₁=V₂/T₂. His discovery anticipated Joseph Louis Gay-Lussac's published law of the expansion of gases with heat of 1802.

Career

Charles was elected to the Académie des Sciences, in 1793, and subsequently became professor of physics at the Conservatoire des Arts et Métiers. He was married to a creole wife. He died in Paris on April 7 1823.
