What are the 4 types of energy transfer and how do they differ from each other?

The four types of energy transfer are conduction, convection, radiation, and mechanical.

Conduction is the transfer of heat through direct contact between objects. Convection is the transfer of heat through the movement of fluids or gases. Radiation is the transfer of heat through electromagnetic waves. Mechanical energy transfer involves the movement of objects transferring energy.

These types differ in how heat is transferred, with conduction and convection requiring a medium, while radiation can occur in a vacuum. Mechanical energy transfer involves the movement of objects to transfer energy.
