An ice-making machine inside a refrigerator operates in a carnot cycle. it takes heat from liquid water at 0.0 degrees celsius and rejects heat to a room at a temperature of 19.2 degrees celsius. suppose that liquid water with a mass of 76.3kg at 0.0 degrees celsius is converted to ice at the same temperature. take the heat of fusion for water to be l_f = 3.34*10^5 j/kg. how much energy e must be supplied to the device? express your answer in joules.
m = Mass of water = 74.6 kg
= Latent heat of fusion =
We have the equation for cold body
We have the equation
Energy rejected to the room is 26667799.8902 J
Energy supplied to the device is given by
The energy supplied to the device is 1751399.8902 J
