A piston - cylinder device whose piston is resting on top of a set of stops initially contains 0.5 kg of carbon dioxide gas at 125 kPa and 30\ deg C. The mass of the piston is such that 450 kPa of pressure is required to raise it. How much heat must be transferred to the carbon dioxide before the piston starts rising? Answer (2 decimal places) Heat transfer:KJ
