An Ideal Carnot Refrigerator Powered from an Electrical Outlet Takes $0.0 ^ { \circ } \mathrm { C }$

Short Answer

An ideal Carnot refrigerator powered from an electrical outlet takes heat from water at $0.0 ^ { \circ } \mathrm { C }$ and rejects heat to a room at $20.0 ^ { \circ } \mathrm { C }$ . How much electrical energy must be supplied to the refrigerator so it will convert $78 \mathrm {~g}$ of water at $0.0 ^ { \circ } \mathrm { C }$ to ice at $0.0 ^ { \circ } \mathrm { C }$ . The latent heat of fusion of water is $3.34 \times 10 ^ { 5 } \mathrm {~J} / \mathrm { kg }$ .
