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.

Question

Copper wires used to transport electrical current heat up
because of the resistance in the wire. If a 140-g wire gains
280 J of heat, what is the change in temperature in the
wire? Copper has a specific heat of 0.384 J gl °C-'.
