10.0 kgm of air is contained in a cylinder by a free-floating, frictionless piston. Initially the air is at 27 C and occupies a volume of 2.87 m^3 and the piston is resting on a set of stops. Heat is transferred to the air until the volume is doubled, but the piston won't move until the pressure inside reaches 400kPa.
a.) What is the temperature inside when the piston starts to move? (C)
b.) What is the final temperature? (C)
c.) What is the total work done? (kJ)
d.) What is the total heat transfer? (kJ)
