There are three copper blocks, A, B, and C, containing 10 kJ of energy at 600 C, 200 C, and 100C, respectively, and a fourth iron block, D, containing 10 kJ of mechanical energy. (Thus, all devices have the same amount of energy.) The surrounding temperature is 25 C. Which of the following is true?
A) All devices have same quality of energy
B) Quality of energy from highest to lowest is : A, B, C, D
C) Quality of energy from highest to lowest is : C, B, A, D
D) Quality of energy from highest to lowest is : D, C, B, A
E) Quality of energy from highest to lowest is : D, A, B, C

Amount of heat added during process-piston-cylinder device
: A piston-cylinder device holds 2 kg of refrigerant fluid R-134a, initially at 500 KPa. At this state, 0.5 kg of the fluid is in the liquid phase. Heat is then added to the fluid at constant pressure to increase its temperature to 60 c.
