SAQ : State Charles’ law. Give its mathematical form

Charle’s law: At constant pressure, the volume of a given mass of a gas increases or decreases by 1/273 of its volume at 0°C for each one-degree rise or fall in temperature.

The mathematical form of Charle’s law:

V_t=Vo(1+t/273)

V_o = volume at 0°C

V_t = volume at t°C
