Question

For one mole of an ideal gas, which of these statements must be true ? (a) U and H each depends only on temperature (b) Compressibility factor z is not equal to 1 (c) CP, m –CV, m = R (d) dU = CVdT for any process

(A) (b), (c) and (d)
(B) (a) and (c)
(C) (a), (c) and (d)
(D) (c) and (d)

Prashant Kotian · Accepted Answer

Correct answer: C. (a) For ideal gas U and H are function of Temprature U = f nRT (c) CP – CV = R (d) U = CVdT for all processes
