b. A freezer you got from a student sale has an inside temperature of – 10C; the temperature in your dorm room is around 20C; assume the freezer is a Carnot engine; furthermore, the insulation is not perfect, and allows for heat to enter the freezer at a rate of 0.1 W. How much power is needed (in the freezer motor) to maintain the constant inside temperature? You are putting 1 liter room-temperature water in ice-cube trays into the freezer...

An ideal Refrigerator Operates between two reservoirs one of Temperature= 400 K and one of Temperature= 320 K. For Every 100 J of heat drawn from the cold reservoir, find: a) the work required b) the heat deposited into the hot reservoir, c) the the coeffcient of performance. Again state how the ideal and real answers would compare.

A sample of ideal gas is placed inside a balloon at room temperature. The balloon is then put inside a freezer, where it deflates without losing any of the gas inside it. The system is the gas inside the balloon. Represent this process with a PV diagram. Represent this process with a work-energy bar chart.

An ice-making machine inside a refrigerator operates in a Carnot cycle. It takes heat from liquid water at 0.0∘C and rejects heat to a room at a temperature of 24.5 ∘C. Suppose that liquid water with a mass of 84.4 kg at 0.0∘C is converted to ice at the same temperature. Take the heat of fusion for water to be Lf = 3.34×105 J/kg . Part A How much heat |QH| is rejected to the room? Express your answer in...
