The water in a deep underground well is used as the cold resevoir of a carnot heat pump that maintains the temperature of a house at 308 k. to deposit 13900 j of heat in the house, the heat pump requires 900 j of work. determine the temperature of the well water.

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
