E2.11 Isochoric Process

Example 2.11: The same gas as in the previous example is cooled from 500 °F to 70 °F at constant volume from initial pressure of 5 atm. Find point and path functions.

Solution

Work added to the system, W (Equation 2.40):

Internal energy change, ΔU

Heat added to the system, Q (Equation 2.41)

Enthalpy change, ΔH:

Entropy change, ΔS (Equation 2.42):
