Question
(1c). (4p) For the following properties listed below, which one is not a function of temperature only
(Depends on other properties):
(A) Specific internal energy u
(B) Specific heat at constant pressure Cp
(C) Specific heat ratio k= Cp/Cv
(D) Total enthalpy H
(E) None of the above
(F) All of the above
(1e). (4p) Circle the valid statement(s) associated with compressed (subcooled) liquid H2O.
(A) Cp >> Cv . (B) Cp ? Cv . (C) c p ? cv = R (D) The effect of temperature on p c and v c is relatively small. (E) The effect of pressure on p c and v c is relatively small.
(1f). (4p) Which line or lines represents the process where the highest boundary work is done from the initial sate to the final state? (A) Process X (B) Process Y (C) Process Z (D) Process X and Y produce the same amount of work (E) Not enough information is given
X, Y 2 1Explanation / Answer
1c.for this answer is (C) because total enthalpy depends on both mass and temperature.
1e.CP-CV=R` is the valid statement among the given statements
1f.ase the area is more for the process X in the p,v diagaram that represents the highest boundary work done
