A gas is confined in a cylinder with a piston that may be pushed in or pulled out. It
is also possible to add heat to or remove heat from the gas independently of the
piston motion. Which of the following combinations of piston motion and
independent heat transfer is certain to increase the temperature of the gas?
Piston Motion Heat
a) No piston motion Removed from the gas
b) Pulled out None transferred
c) Pulled out Added to the gas
d) Pushed in Removed from the gas
e) Pushed in Added to the gas
