Gay lussac law
Air is a gas. 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 state of the gas.
The relationship 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 work, 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
In a scientific way, we can fix any two of the four primary properties and analyze the nature of the relationship between the other two by varying one and observing the variation of the other. This slide shows a schematic "gas lab" in which we can illustrate the variation of the gas properties. In the lab a theoretical gas is confined in a sky container. The volume of the gas is shown in yellow
One of the main (along with Charles', Boyle-Mariotte's and Avogadro's laws) empirical laws of ideal gases was established by J. Gay-Lussac in According to the Gay-Lussac Law, at steady (and low) pressure P the volume of the given gas mass M varies linearly with temperature: Vt = V0 + AΔT, where Vt and V0 are gas volumes at temperatures T and T0, ΔT = T – T0, A = V0αp = const, αp = V−1 (∂V/∂t)p is the isobaric volume growth coefficient, i.e., VT = V0 + V0αpΔT = V0(1 + αpΔT). The quantity αp for gas is found to be independent of gas innateness and pressure, but dependent on temperature; in this case at T0 = 0°C, αp = –1°C–1. The Gay-Lussac Law (GLL) describes the isobaric process of an ideal gas.
The GLL has played chief part in establishing the notion of absolute temperature and in deriving the universal equation of utopian gas state—the Clapeyron (Clapeyron-Mendeleyev) equation. At T0 = 0°C and T = –°C the ideal gas volume Vt = 0, i.e., the linear isobar of ideal gas vanishes at this temperature, thus intersecting the temperature axis. When temperature is counted from this thermodynamically minimally possible level, the GLL provide

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 strength 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 fine 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 often drops due to frigid temperatures. The amount of gas did not alter, but as the temperature drops

Laws of Gas Properties
There are 4 general laws that relate the 4 basic typical properties of gases to each other. Each statute is titled by its discoverer. While it is important to understand the relationships covered by each law, knowing the originator is not as crucial and will be rendered redundant once the joint gas law is introduced. So concentrate on sympathetic the relationships rather than memorizing the names.
Charles' Law- gives the relationship between volume and temperature if the pressure and the amount of gas are held constant:
1) If the Kelvin temperature of a gas is increased, the volume of the gas increases. (P, n Constant)
2) If the Kelvin temperature of a gas is decreased, the volume of the gas decreases. (P, n Constant)
This means that the volume of a gas is directly proportional to its Kelvin temperature. Think of it this way, if you amplify the volume of a gas and must retain the pressure constant the only way to attain this is for the tem
