(5) A spring-loaded piston-cylinder device is filled with 6 kg of steam at 0.8 MPa and 800°C. Initially, the spring exerts no force against the piston. The spring constant in the spring force relation F = kx is k= 0.7 kN/m and the piston area is 683.636 cm². The water now undergoes a process until its volume is reduced by 36%. The final temperature of the water is:
