#10: A heat pump requires 430 W of electrical power to deliver heat to your house at a rate of 2390 J per second. How many joules of energy are extracted from the cold air outside each second? #11: The coefficient of performance for a heat pump is defined as the ratio of the heat delivered to the warmer system to the work required. If a heat pump requires an input of 360 W of electrical energy and has a...
What is the coefficient of performance of an ideal heat pump that extracts heat from 5.0...
What is the coefficient of performance of an ideal heat pump that extracts heat from 5.0 ∘C air outside and deposits heat inside a house at 23 ∘C ? (The answer is 16. COP=16.) If this heat pump operates on 1200 W of electrical power, what is the maximum heat it can deliver into the house each hour? (This is what I am having trouble answering. The answer is not to multiply 16 and 1200 to get 19,200 J, nor...
