Please help solve part (a) and (b). Thank
you.
A Carnot refrigerator (the reverse of a Carnot engine) absorbs heat from the freezer compartment at a temperature of -2degreeC and exhausts it into the room at 25degreeC. How much work must be done by the refrigerator to change 0.30 kg of water at 25degreeC into ice at -2degreeC? If the compressor output is 210 W, what minimum time is needed to accomplish this?

1) 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 24.7 ∘C. Suppose that liquid water with a mass of 76.6 kg at 0.0∘C is converted to ice at the same temperature. Take the specific transformation energy for water to be Lf = 3.34×105 J/kg . Part A:- How much energy E must be supplied to the device? Express your answer...

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 24.9 ∘C. Suppose that liquid water with a mass of 71.5 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 Part complete How much heat |QH| is rejected to the room?...

Each pound of fat contains 3500 food calories. When the body
metabolizes food, 80.5% of this energy goes to heat. Suppose you
decide to run without stopping, an activity that produces 1340 W of
metabolic power for a typical person.
Part A) For how many hours must you run to burn up 1 lb of
fat?
Part B) If you followed your planned exercise program, how much
heat would your body produce when you burn up a pound of fat?...

2. Running up the stairs (5 pts). Time how long it takes for you (or a friend) to run as fast as possible up a staircase. Measure the height of one step and count the steps to find how high you climbed. a) How much mechanical energy did you produce to climb the stairs? b) What was the average mechanical power produced during your climb? c) Estimate the muscle mass in your upper legs (quadriceps, hamstrings, and buttocks). (Recall that...
