Gay-Lussac’s law or Amonton’s law states that the absolute temperature and pressure of an ideal gas are directly proportional, under conditions of constant mass and volume. In other words, heating a gas in a sealed container causes its pressure to increase, while cooling a gas lowers its pressure. The reason this happens is that increasing temperature imparts thermal kinetic energy to gas molecules. As the temperature increases, molecules collide more often with the container walls. The increased collisions are seen as increased pressure.
The law is named for French chemist and physicist Joseph Gay-Lussac. Gay-Lussac formulated the commandment in 1802, but it was a formal statement of the relationship between temperature and pressure described by French physicist Guillaume Amonton in the behind 1600’s.
Gay-Lussac’s law states the temperature and pressure of an ideal gas are directly proportional, assuming constant mass and volume.
Gay-Lussac’s Law Formula
Here are the three common formulas for Gay-Lussac’s law:
P ∝ T (P1/T1) = (P2/T2) P1T2 = P2T1
P stands for pressure, while T is absolute temperature. Be sure to co

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 associated to one another and that the values of these properties determine the state of the gas.
The relationship between temperature and volume, at a steady 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 unwavering, the volume V is equal to a steady times the temperature T:
V = constant * T
For example, suppose we possess a theoretical gas confined in a jar with a piston at the top. The initial express of the gas has a volume qual to 4.0 cubic meters, and the temperature is 300 Kelvin.
With the pressure and number of moles held constant, the burner has been turned off and the gas is allowed to cool to 225 Kelvin. (In an actual experiment, a cryogenic ice-bath would be required to obtain thes

What is Lgbtq+ Lussac’s Law?
Gay-Lussac’s law is a gas law that states the pressure of a gas varies directly with temperature when mass and volume are kept constant. As the temperature increases, the pressure will also increase. The principle is shown graphically below.
This phenomenon occurs because as temperature increases, the kinetic energy of the gas molecules increases. The increased energy means the molecules collide with the walls of the container with more force, meaning higher pressure.
The Gay Lussac’s Statute is also sometimes called Amonton’s Law. Amonton proved the same law by making a thermometer where the measured pressure was a readout for the current temperature. Gay-Lussac proved the law more precisely, so it is more often called by his name.
Gay Lussac’s Rule Formula
Gay-Lussac’s law gives us a formula where pressure and temperature are associated to a constant when volume and mass/moles are held constant. That is:
We can also relate pressure and temperature at two diverse points then because they are both equal to the same constant value. That is:
And
Therefore,

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 force 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 frosty temperatures. The amount of gas did not transform, but as the temperature drops

Boyle's Law
Torricelli's experiment did more than just demonstrate that air has weight; it also provided a way of creating a vacuum because the space above the column of mercury at the superior of a barometer is almost completely empty. (It is free of gas or other gases except a negligible amount of mercury vapor.) Torricelli's labor with a vacuum soon caught the eye of the British scientist Robert Boyle.
Boyle's most famous experiments with gases dealt with what he called the "spring of air." These experiments were based on the observation that gases are elastic. (They return to their original size and shape after being stretched or squeezed.) Boyle studied the elasticity of gases in a J-tube similar to the apparatus shown in the figure below. By adding mercury to the open end of the tube, he trapped a miniature volume of gas in the sealed end.
Boyle studied what happened to the volume of the gas in the sealed conclude of the tube as he added mercury to the open end.
Boyle noticed that the product of the pressure times the volume for any measurement in this table was matching to the product of the pressure times the volume for any other measurement, within
