Question: A piston - cylinder assembly initially contains 0 . 5 kg of helium gas at 1 0 0 kPa and 2 5 deg C

A piston-cylinder assembly initially contains 0.5 kg of helium gas at 100 kPa and 25\deg C. In this case, the piston is on the stoppers. The pressure must be 500 kPa for the piston to move. How much heat must be transferred to the helium to move the piston
