What two quantities are studied in Gay-Lussac’s’ Law*

Gay-Lussac's Law studies the relationship between the pressure and temperature of a gas. The two quantities studied in this law are:

1. Pressure: This is the force exerted by the gas per unit area on its container. It is usually measured in units like atmospheres (atm), pascals (Pa), or torr.

2. Temperature: This is a measure of the average kinetic energy of the particles in a substance. In the context of Gay-Lussac's Law, it is usually measured in Kelvin (K), which is an absolute temperature scale.

According to Gay-Lussac's Law, the pressure of a gas is directly proportional to its absolute temperature, provided the volume of the gas is kept constant. This means that if the temperature of a gas increases, its pressure also increases, and vice versa.
