An ice-making machine operates in a Carnot cycle. It takes heat from water at 0.0º C and rejects heat to a room of temperature 22.5º C. Suppose that a mass 79.5 kg of water at 0.0° C is converted to ice at 0.0° C.
How much heat is rejected to the room?
|QH| = J
Part B
How much energy must be supplied to the device?
|W| = J
♦ Relevant knowledge
