A piston compresses 1 kg of air inside a cylinder as shown
The rate at which the piston does work on the air is 3000 W. At the same time, heat is being lost through the walls of the cylinder at a rate of 847.5 W.
Given that the specific heats of air at constant pressure and volume are cp=1004.5 J/kg-K
cv=717.5 J/kg-K respectively, the corresponding change in the temperature of the air is
