Concept explainers

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

You have decided now that quarantine is about over to take a trip to Hawaii. You decide to rent a small house that has floor to ceiling windows. It is small so it is one floor. The length and width of the windows are 9m x 14m. There are 4 of them. It is a constant 950F (350C) outside and you really like it 650F(180C) inside. You have an air conditioner that operates at 75 percent Carnot efficiency. The windows are 6cm thick and the rest of the house is well insulated. a) How much electrical energy do you use in a day? b) What is the cooling capacity each day?
