In a Steam Engine,steam in a Cylinder Is Compressed by a Piston

In a steam engine,steam in a cylinder is compressed by a piston exerting 13.5 atm of external pressure.The volume of the cylinder decreases by 20.1 L and simultaneously the steam heats up.If the total energy change of the steam is 32.8 kJ,calculate the heat flow into/out of the steam.(101.3 J = 1 L . atm)

A) +239 J
B) +27.5 kJ
C) -27.5 kJ
D) +5310 J
E) -5310 J
