At constant volume, pressure of a fixed amount of a gas varies directly with the temperature, is
Gay Lussac's law
Gay Lussac's law states that the pressure of a fixed mass of a gas at constant volume is directly proportional to the temperature on Kelvin scale.
At constant temperature, the pressure of a fixed amount of gas varies inversely with its volume, is
The pressure of a given mass of gas at constant volume varies with temperature as
At constant pressure, the volume of a fixed mass of a gas is directly proportional to its absolute temperature, is
