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) 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), (c) and (d)
(a) and (c)
(c) and (d)
(b), (c) and (d)
Explanation
For 1 mole of ideal gas :
1. Both internal energy (U) and Enthalpy (H) depends on temperature
2. Compressibility factor Z = 1
3. CP, m – CV, m = R
4. dU = CVdT for all process
1. Both internal energy (U) and Enthalpy (H) depends on temperature
2. Compressibility factor Z = 1
3. CP, m – CV, m = R
4. dU = CVdT for all process
