A refrigerator is connected to a generator powered by a fuel
with a calorific value of 35000 kJ/kg and a density of 0.85 g/cm3 .
The inside temperature of the refrigerator is 0°C, and the outside
temperature is 20°C. a. How much work is required to freeze 500 g
of water?
ΔfreezingH° = 6.02 kJ mol– 1 ) b. How much internal energy
change occurs during the process? c. Since the generator consumes 5
L of fuel per hour, calculate the thermal efficiency of this
engine.
