P1) (25 points) Air is contained in a cylinder device fitted with a piston-cylinder. The piston initially rests on a set of stops, and a pressure of 250 kPa is required to move the piston. Initially, the air is at 100 kPa and 23 °C and occupies a volume of 0.25 m3. Determine the amount of heat transferred to the air, in kJ, while increasing the temperature to 750 K.
