Question
Just true or false with an explanation
c) (T or F) The derivative (8U/aV)T 0 for an ideal gas, but is generally non-zero for
other types of matter (e.g. liquids, solids).
d) (T or F) You pour a glass of water (initially at room temperature) into a very large
pot of hot water at 350 K and 200 k.J of heat is transferred. The entropy change for the
water that was originally in the glass is ASys=(200 kJ)/(350 K) .

a) (T or F) ASays = 0 for a gas expanding adiabatically into a vacuum.
b) (T or F) A reversible heat engine will always have the same efficiency for a given
Thot/Tcold; no matter what material/substance it is made of.
c) (T or F) The derivative (öU/ƏV)T = 0 for an ideal gas, but is generally non-zero for
other types of matter (e.g. liquids, solids).
