Gay-Lussac's Law

Gay-Lussac's Law states that the pressure of a given mass of gas varies directly with the absolute temperature when the volume is kept constant. In this formula, P1 represents the initial pressure, T1 is the initial absolute temperature, and P2 is the final pressure of the gas. T2 is the final absolute temperature. Absolute temperatures are always measured in Kelvin. If you need to convert from Celsius to Kelvin, simply add 273.15 to the Celsius temperature.

It is essential to maintain the same temperature scale when using this formula, and it's commonly practiced to use Kelvin for such gas law calculations. This formula can be helpful in a variety of practical applications, such as calculating the pressure changes in a heated system or understanding the behavior of ideal gases under different temperatures while maintaining a constant volume.
