Problem I: What is the coefficient of performance of an ideal heat pump that extracts heat from 7.0oC air outside and deposits heat inside a house at 22oC?
Problem II: If this heat pump operates on 1100 W of electrical power, what is the maximum heat it can deliver into the house each hour?
Show the process and each step.
