A mass of 10-g of nitrogen is contained in the spring loaded piston-cylinder device shown in Fig. P5-57. The spring constant is 1 kN/m, and the piston Diameter is 10 em. When the spring exerts no force against the piston, the nitrogen is at 120 kPa and 27°e. The device is now heated until its volume is 10 percent greater than the original volume. Determine the change in the specific internal energy and enthalpy of the nitrogen.
