Final answer:
The transfer of heat through direct contact is called conduction (option 1). Convection is heat transfer by fluid movement, while radiation transfers heat via electromagnetic waves.
Step-by-step explanation:
The method of heat transfer that occurs when heat moves from one body to another by direct contact is known as conduction. This process takes place at the molecular level, where heat is transferred through stationary matter by physical contact without any macroscopic movement of the material itself. An example of conduction is heat passing from the hot burner of a stove through the metal of a pan to the food inside the pan.
Convection and radiation are the other two methods of heat transfer. Convection involves the macroscopic movement of a fluid such as air or water, and radiation involves the transfer of energy through electromagnetic waves.
