# Ideal Gases and Final Temperatures

1. Given that (dU/dV)T = 0 for an ideal gas, prove that (dH/dV)T = 0 for an ideal gas.

2. Calculate the final temperature, the work done, and the change of internal energy when 0.200 mol NH3 is used in a reversible adiabatic expansion form 0.50 dm3 to 2.00 dm3, initially at 25oC. The molar heat capacity of NH3 is 27.0 JK-1mol-1
