Aheat pump has a coefficient of performance of 3.0 and is rated to do work at 1500 w. a. how much heat can it add to a room per second? b. if the heat pump acted as an air conditioner in the summer, what would you expectits coefficient of performance to be assuming all else stay the same? what is the rise in temperature of the air in the room in part (a) if the heat pump is run for 5 minutes? assume (unrealistically) no loss of heat from the room (of dimensions 10m x8m x 3m), and for ease of calculation assume air composed of only nitrogen (molar mass 2be, density at ambient temps 1.25 kg/m3)
