This is Problem 13 of Chapter 3 in Sustainable Energy by Richard Dunlap, 2nd Edition. I need help solving it: A coal-fired generating station has an efficiency of 38% and produces an average electrical output of 1000 MWe.(a) How much coal does it burn per second (kg/s)? Assume the coal is bituminous.(b) How much heat (in joules) is released to the environment per second?(c) How many liters of water at 20°C could the heat in part (b) boil (at STP) per second? For c, here is my idea: use Q = mc(change in T). Here change in T is (100 C - 20 C) or 80 C and c = 4200 J/(kg C) so I can solve for m. Question: I need the density of water to find liters, but density changes with temperature. So, do I use the regular 1000 kg/m^3 or something else?

An air conditioning unit works by taking heat out of a room. As the refrigerant gas expands in the cooling coils, it absorbs heat from the circulating air in the room. This heat is then released as the refrigerant is compressed by the part of the unit that is directed out of the room. The unit serves like a heat pump for the room. Since a refrigerator works in a similar manner, can t also be used to maintain a cool temperature inside a room? Justify your answer.
