Problem: 9.00 moles of a monatomic ideal gas undergoes an adiabatic expansion (adiabatic means Q = 0). The initial pressure is 4.00 x 10 5 Pa and the initial volume is 0.300 m3. The final pressure is 2.48 x 105 Pa and the final volume is 0.400 m 3. How much work is done by the gas? Be sure to say if the work done is positive or negative.
