Charle’s Law

According to Charle’s Law, the volume (V) of a definite quantity of gas is directly proportional to its absolute temperature (T), at constant pressure (P).

V œ T (Pressure constant)
V = KT K = Constant
V/T = K
Similarly
V1/T1 = V2/T2

Here we have temperature in a Kelvin temperature or absolute temperature. The temperature at which the volume of hypothetical gas will be zero is called as Kelvin temperature or absolute temperature. Kelvin has discovered this and the temperature is -273°C. The relation between Kelvin temperature (T) and Celsius temperature (t) is shown below.

T = t + 273
