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/kgAssume 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?H_cold = Q_cold/time =
