A refrigerator maintains a temperature of $0^{\circ} \mathrm{C}$ in the cold compartment with a room temperature of $25.0^{\circ} \mathrm{C} .$ It removes energy from the cold compartment at the rate of 8000 $\mathrm{kJ} / \mathrm{h}$ (a) What minimum power is required to operate the refrigerator? (b) The refrigerator exhausts energy into the room at what rate?
A refrigerator maintains a temperature of $0^{\circ} \mathrm{C}$ in the cold compartment with a room temperature of $25.0^{\circ} \mathrm{C}$. It removes energy from the cold compartment at the rate $8000 \mathrm{~kJ} / \mathrm{h}$. (a) What minimum power is required to operate the refrigerator? (b) At what rate does the refrigerator exhaust energy into the room?
A refrigerator is removing heat from a cold medium at $3^{\circ} \mathrm{C}$ at a rate of $7200 \mathrm{kJ} / \mathrm{h}$ and rejecting the waste heat to a medium at $30^{\circ} \mathrm{C}$. If the coefficient of performance of the refrigerator is $2,$ the power consumed by the refrigerator is $(a) 0.1 \mathrm{kW}$ (b) $0.5 \mathrm{kW}$ $(c) 1.0 \mathrm{kW}$ $(d) 2.0 \mathrm{kW}$ $(e) 5.0 \mathrm{kW}$
