1. The problem statement, all variables and given/known data A monatomic ideal gas is compressed adiabatically from a pressure of 1.19e5 Pa and volume of 250 L to a volume of 32.0 L. (a) What is the new pressure of the gas in Pa? (b) How much work is done on the gas? 2. Relevant equations I know that W= Average P (Delta V) 3. The attempt at a solution I used P (v^(5/3)) = P (V^(5/3)) to solve for P2, and i got 3.6e6 Pa which was correct Now I just need help in solving for part b, the work done on the gas. I tried finding the average pressure between the two pressures and multiplying it by the change in volume, but Webassign said it was an incorrect answer. Any help please?
