Temperature is used to increase the volume of gas

, the answer is Charles' Law!

The correct value for the universal gas constant is

Values of general gas constant are: (value dependant on units)

R = 0.08205746 [atm. ℓ.mol-1.K-1]

R = 8.314472 [Pa.m3.mol-1.K-1 or J.mol-1.K-1]

R = 1.99 [Cal.mol-1.K-1]

An increase in gas pressure is a result of an increase in molecular collisions
