3. (4-55) A mass of 10 g of nitrogen is contained in the spring-loaded piston-cylinder device shown below. The spring constant is 1 kN/m, and the piston diameter is 10 cm. When the spring exerts no force against the piston, the nitrogen is at 120 kPa and 27 C. 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. Nitrogen - Spring 3.
