A spring-loaded piston cylinder device contains 2-ft3 of air. The spring constant is 10 lbf/in and its piston diameter is 15 inches. The state of the air is 260 psia at 565 degrees Fahrenheit when no force is exerted by the spring on the piston. This device is now cooled until the volume is half its original size. What is the change in the specific internal energy and enthalpy of th
