Answer:
Charles' Law
Step-by-step explanation:
Charles' law gives the relationship between the the volume of a fixed mass of a gas and the absolute temperature.
It states that, Provided the pressure of a fixed mass of a gas remains constant, the volume of a fixed mass of a gas is directly proportional to the absolute temperature.
V/T= constant
When one of the conditions either temperature of volume changes under the same pressure, then the relationship.
V1T2= V2T1 is true
