Answer: conduction
convection
radiation
Step-by-step explanation:
Heat is a form of energy which is called as thermal energy. The heat is transferred from one body to another or from one medium to another by three methods:
The three methods includes the conduction, convection and radiation. The conduction
Conduction: This involves the transfer of heat through direct contact of the solid bodies. The heat travels from a warmer entity or body to the colder entity or body.
Convection: This involves the transfer of heat when the warmer areas of a typical liquid or gas moves to the cooler areas of the liquid or gas.
Radiation: This involves the transfer of the heat energy through electromagnetic radiations like ultraviolet and infrared.
