A 752-cm sample of water was placed in a 1.00-kg aluminum pan. The inital temperature of the pan was 26°C and the final temperature of the system was 39°C. What was the initial temperature of the water

Determine the specific heat capacities at constant volume and constant pressure for nitrogen, given that its molecular weight is 28 and the adiabatic index for expansion and compression is 1.4. The universal gas constant is 8314 Jmol-1K-1.  Explain the difference in the values for the two specific heat capacities.

3-39 Water initially at 200 kPa and 300°C is contained in a piston-cylinder device fitted with stops. The water is allowed to cool at constant pressure until it exists as a saturated vapor and the piston rests on the stops. Then the water continues to cool until the pressure is 100 kPa.
