Argon, a monatomic ideal gas, is contained in a special balloon that is a perfect thermal insulator at 300 K and 1 atm. The balloon is free to compress as the environment pressure is raised to 2 atm. What is the final temperature of the gas? Do I assume that the question is describing an adiabatic compression? But I don't have the volume
The simple answer is 2/1*300k but it does not consider the reduction in pressure caused by the balloon shrinking. If the balloon is under tension at 1atm that tension would also add to some to the compression of the gas. If it is not under tension 2atm it would not add to the compression of the gas. Do I assume that the question is describing an adiabatic compression? YES - special balloon that is a perfect thermal insulator But I don't have the volume: volume will be 1/2 at 2atm. You can say volume=2 at 1atm and 1 at 2atm
