Gay lussac
Gases have various properties that we can observe with our senses, including the gas pressure,temperature (T), mass, and the volume (V) that contains the gas. Careful, scientific observation has determined that these variables are related to one another and that the values of these properties determine the mention of the gas.
The bond between temperature and volume, at a constant number of moles and pressure, is called Charles and Gay-Lussac's Law in honor of the two French scientists who first investigated this relationship. Charles did the original perform, which was verified by Gay-Lussac. They observed that if the pressure is held constant, the volume V is equal to a constant times the temperature T:
For example, suppose we hold a theoretical gas confined in a jar with a piston at the top. The initial mention of the gas has a volume qual to cubic meters, and the temperature is degrees Kelvin. With the pressure and number of moles held constant, the burner has been turned off and the gas is allowed to cool to degrees Kelvin. (In an actual experiment, a cryogenic ic
Joseph Louis Gay-Lussac data for kids
Joseph Louis Gay-Lussac (born December 6, – died May 9, ) was a notable Frenchchemist and physicist. He is optimal known for revealing that water is made of two parts hydrogen and one part oxygen, which he did with Alexander von Humboldt. He also created two essential laws about gases. His work on alcohol and liquid mixtures led to the "degrees Gay-Lussac" scale, which is still used today to measure how much alcohol is in drinks in many countries.
Joseph Louis Gay-Lussac's Life Story
Gay-Lussac was born in Saint-Léonard-de-Noblat, a town in France. His father was a lawyer and decide. The family later added "Lussac" to their name, becoming Gay-Lussac.
He started his education with the Catholic Abbey of Bourdeix. Later, he moved to Paris to continue his studies. In , he entered the École Polytechnique, a famous science college. His father was in prison during this time because of the French Revolution.
After three years, Gay-Lussac moved to the École Nationale des Ponts et Chaussées. Soon after, he became an assistant to Claude Louis Bertholl

The Expansion of Gases by Heat[1]

Oppose of this Memoir
For many years physicists have studied the expansion of gases; but the results which they obtained showed such great differences that instead of reaching a definite finding they render further examination desirable.
The expansion of vapors has been given less consideration, although we have known for many years the prodigious effects of water vapor; and although we have made most fortunate applications of these effects, Zeigler and Bettancourt are the only ones, so far as I perceive , who have tried to measure them. Their experiments cannot grant the true expansion of this vapor; for since they always had water in their apparatus, for each new degree of heat they had the enlargement of the vapor formed by the preceding degrees of heat, and an increase of volume by the formation of fresh vapor; two causes which manifestly conspire to raise the mercury

What is Gay-Lussac's Law?
It is a law describing the properties of gases. It is also sometimes referred to as Amonton's law or the pressure-temperature law. The law states that:
An amount of gas in a closed container (at a constant volume) has a pressure that will vary proportionally to the absolute temperature.
The mathematical representation for this law is:
PT = k or P∝T
Where, P= pressure, T=temperature, and k= constant.
Importance of Gay-Lussac's Law
Let's think about the gas molecules in a closed system. If the temperature increases, the molecules of gas will have more energy. They will move around more and expand. This causes an increase in pressure. If the temperature decreases, the molecules lose power and are closer together. So, the pressure decrease.
A great example of Gay-Lussac's law is the tires on your vehicle. If the tire has no punctures and a nice seal, it is a closed container. There is a specific amount of gas or mass of gas in that container. In the winter, the pressure in tires o
