Some homes that use baseboard heating use copper tubing. Hot water runs through and heats the copper tubing, which in turn heats aluminum fins. It is actually the aluminum f that heat the air rising through the fins. How much energy would it take to heat a section of the copper tubing that weighs about 5400 g. from 15.01 "C to 25.48 °C? Copper has a specific heat of 0.3850 J/(8 °C) Express your answer to four significant figures.

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.
