**Enter 'x' in the field to be calculated.**The law of Gay-Lussac tells us that at constant volume, the volume of a ideal gas is proportional to its temperature. Therefore, for two different states 1 and 2 of the same gas, at constant volume,

`P_2 / T_2 = P_1 / T_1`

P_{1}: pressure in state 1 in pascal (Pa)

T_{1}: temperature in state 1 in Kelvin (K)

P_{2}: pressure in state 2 in pascal (Pa)

P_{2}: temperature in state 2 in Kelvin (K)
