How Does Heat Expansion Affect Gas Temperature?

[KingTutATL]

Heat is supplised to a sample of a monatomic ideal gas at 40C. It is observed that the gas expands until its volume is doubled and the pressure drops to half of its original value. What is the final temperature of the gas? How do you solve? pv=nRt R and n are constant so do you have (P1V1)/(T1)=(P2V2)T2?

You've got it. The question is a bit confusing because the gas does not expand due to the supply of heat. It draws heat from its surroundings as it expands.
