A vertical piston culli marks) process, 65kw w fylinder device contains water and is being heated on top of a range. During the 8KW. The plof heat is transferred to the water, and heut losses from the side walls amount to Determine piston rises as a result of evaporation, and 5KW of work is done by the vapor. Determine the change in the energy of the water for this process. A vertical piston-cylinder device contains water and is being heated on top of a range.
