A system consists of two very large thermal reservoirs in contact with each other, one at temperature 300C and the other at temperature 200C.
When 600 J of heat transfers from the 300C reservoir to the 200C reservoir, what is the change in entropy of this system?
A) 0.221 J/K
B) 1.00 J/K
C) 5.00 J/K
D) -1.00 J/K
E) -2.31 J/K
Question 2
An ideal Carnot engine operates between reservoirs having temperatures of 125C and -20C. Each cycle the heat expelled by this engine is used to melt 30.0 g of ice at 0.00C.
The heat of fusion of water is 3.34 105 J/kg and the heat of vaporization of water is
2.25 106 J/kg.
(a) How much work does this engine do each cycle?
(b) How much heat per cycle does this engine absorb at the hot reservoir?
What will be an ideal response?
