The pressure of two moles of a perfect gas at 22C changes from 200 kPa to 300 kPa during an isothermal process.

a) What is the work done by the gas?

b) How much heat is absorbed or released during the process by the gas?

Question 9 (10 points)

The pressure of two moles of a perfect gas changes from 200 kPa to 300 kPa during a process at constant volume. The initial temperature of the gas is 22C. The adiabatic constant of the gas is 5/3 and Cp = 20.8 J/(mol.K)

a) What is the work done by the gas?

b) What is the change in the gas's internal energy?
