Evaluate the entropy change, Chemistry

Assignment Help:

A house is air conditioned using solar energy.  Solar radiation heats a pressurized tank such that the temperature is maintained at 175oC.  1500 kJ must be extracted from the house to maintain the temperature at 24oC when the ambient temperature is 33oC.

Determine the minimum amount of heat that must be extracted from the tank of water by any device built to accomplish the required cooling of the house

A 2kg piece of copper at 200oC is taken out of a furnace and is allowed to cool in air with an ambient temperature of 25oC.  Calculate the entropy change in the universe as a result of this process.  The Cp of copper is 0.38 kJ/kg K.
