For one mole of an ideal gas, which of these statements must be true? (a) Internal energy ( U ) and enthalpy ( H ) each depends on temperature. (b) Compressibility factor Z is not equal to 1 (c) C P , m – C V , m = R (d) dU = C v dT for any process

Options

  1. A(a) and (c)
  2. B(b), (c) and (d)
  3. C(c) and (d)
  4. D(a), (c) and (d)

Correct answer

D. (a), (c) and (d)

Step-by-step solution

(a) For ideal gas, U and H are functions of temperature U = f 2 RT where f is total degree of freedom. (b) Compressibility factor (Z) is equal to 1 for ideal gas. (c) C P , m − C V , m = R (d) ΔU = C v dT for all processes
