Final answer:
Heat transfer can occur through conduction, convection, and radiation. Conduction is when heat is transferred through direct contact, convection is when heat is transferred through the movement of a fluid, and radiation is when heat is transferred through electromagnetic waves.
Step-by-step explanation:
The three methods of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat between two objects in direct contact with each other. An example of conduction is when a metal spoon sitting in hot soup gets hot.
Convection is heat transfer by the movement of mass, such as hot air rising and cool air sinking. An example of convection is a pot of water boiling on a stove. Radiation is heat transfer by electromagnetic waves, such as heat from the sun reaching the Earth. An example of radiation is feeling warm standing close to a bonfire.
