A vertical piston-cylinder that initially has a volume of 0.2m^3 is filled with 0.2kg of air. The piston is weighed so that the pressure on the air is always maintained @ 2 bars. Heat transfer is allowed to take place until the volume is 75% of its initial value.
Determine A) the initial and final temperature of the air in K. and B) the quantity and direction of the heat transfer in KJ. Air is modeled as an ideal gas.
