Suppose that you want to freeze 1 kg of water for a party, and only have 5 minutes to do it. relying on nothing but your keen physical abilities, a dixicup, duct tape and a piece of string, you manage to build a refrigerator unit which can do the job. the temperature inside the refrigeration unit is 273 k, and the temperature outside is 350 k. since you are a brilliant uiuc student, assume that your refrigerator has the maximum possible efficiency. the latent heat of fusion of water is 3.33×105 j/kg assume that the initial temperature of the water is 273 k. 1) what is the heat flow ( q_ cold/time ) out of the cold well per second in j/s?
