In a vertical piston-cylinder device, the piston is resting on a set of stops 0.082 m above the inner bottom surface of the cylinder. The cylinder contains CO2 initially at –20 C and 60 kPa. The mass of the piston is 1.5 kg and its diameter is 0.06 m. Assuming that the atmospheric pressure outside the device is 101 kPa, determine how much heat must be added to just lift the piston off the stops
