**Enter 'x' in the field to be calculated.**Charles's law tells us that at constant pressure, the volume of an ideal gas is proportional to its temperature. Therefore, for two different states 1 and 2 of the same gas, at constant pressure,

`V_2 / T_2 = V_1 / T_1`

V_{1}: volume in state 1 in cubic meter

T_{1}: temperature in state 1 in Kelvin

V_{2}: volume in state 2 in cubic meter

P_{2}: temperature in state 2 in Kelvin
