3. Use the above result to calculate (VCV)T for water at T=300C and P=30bar. 4. Using the steam tables, complete the table below to arrive at an estimate for VCV at 300C and 30 bar. How does this experimental value compare to that obtained in problem \#3? 5. Use the pressure-enthalpy diagram for methane to develop a table similar to problem \#4, then estimate for VCV for methane at 300K and 30 bar. Compare this to (VCV)T calculated using your result in problem \#2. Can you make a general statement regarding the accuracy of using cubic equations of state to estimate changes in heat capacities
