Example 2.10: The same gas as in the previous example is cooled from 500 °F to 70 °F at constant pressure of 5 atm. Find point and path functions.
Solution:
Initial volume, V1:
Final volume, V2 (Equation 2.38):
Internal energy change, ΔU:
Work done by the system, W (Equation 2.39):
Heat added to the system, Q (Equation 2.36)
Entropy change, ΔS (Equation 2.37):
