Gay-Lussac’s Law
Gay-Lussac’s Law states that the pressure of a gas is directly proportional to its temperature when the volume remains constant. In simpler terms, as the temperature of a gas increases, its pressure also increases, assuming the volume remains unchanged. This relationship can be expressed mathematically as P₁/T₁ = P₂/T₂, where P₁ and T₁ stand for the initial pressure and temperature, and P₂ and T₂ represent the last pressure and temperature. This law highlights the importance of temperature control in gas-related applications, such as gas storage and transportation, to maintain desired pressure levels.
What is Gay-Lussac’s Law?
Gay-Lussac’s Law, also known as the Pressure-Temperature Law, describes the relationship between the pressure and temperature of a gas when the volume remains continual. It states that the pressure of a gas is directly proportional to its temperature, assuming the volume and amount of gas remain constant.
Mathematically, Gay-Lussac’s Law can be expressed as:
P₁/T₁ = P₂/T₂
Where:
P₁ represents the initial pressure of the gas T₁ represents the initial temperature of the gas P₂ represents the final pressure of the gas

The content that follows is the substance of lecture 18. In this lecture we cover the Gas Laws: Charles',Boyle's,Avagadro's and Gay Lussacs as well as the Optimal and Combined Gas Laws.
Laws of Gas Properties
There are 4 general laws that relate the 4 basic characteristic properties of gases to each other. Each law is titled by its discoverer. While it is important to comprehend the relationships covered by each law, knowing the originator is not as important and will be rendered redundant once the combined gas law is introduced. So concentrate on understanding the relationships rather than memorizing the names.
Charles' Law- gives the bond 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 increase the volume of a gas and must keep the pressure unchanging the only way to achieve this is for the
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 ethics of these properties determine the mention 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 unique work, which was verified by Gay-Lussac. They observed that if the pressure is held continual, the volume V is equal to a constant times the temperature T:
For example, suppose we possess a theoretical gas confined in a jar with a piston at the top. The initial state 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 continual, 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 these temperatures.) As the gas cools, the volume decreases to 3.0 cu
Gay-Lussac's Law
Gay-Lussac's law is a gas law which states that the pressure (P) exerted by a gas (of a given mass and kept at a unchanging volume) varies directly with the absolute temperature of the gas.
T ∝ P or P = constant * T
In other words, if an ideal gas is confined in a container whose volume can not be changed, and the temperature is increased, then the pressure should increase proportionally to the temperature.
The apparatus for the experiment is shown above. A temperature sensor and gas sensor are placed inside the glass bulb to measure the pressure and temperature of the gas. Since the glass bulb cannot stretch the volume is fixed. The bulb is placed in ice and allowed to cool for a time. When the temperature in the bulb drops the heater is turned on and as the temperature in the bulb rises the temperaure and pressure values ar etaken and graphed.

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 excellent 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 freezing temperatures. The amount of gas did not convert , but as the temperature drops
