Explanation:

Conduction is the method of transfer of heat within a body or from one body to the other due to the transfer of heat by molecules vibrating at their mean positions.

Convection is the mode of heat transfer which occurs mostly in liquids and gases.

Radiation is another form of heat transfer. It does not require any medium and can be used for transfer of heat in a vacuum as well.

Answer:

 Transferring - Heat

All matter is made up of molecules and atoms. These atoms are always in different types of motion (translation, rotational, vibrational). The motion of atoms and molecules creates heat or thermal energy.

Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat.

Conduction :-

Conduction is the transfer of heat between substances that are in direct contact with each other. The better the conductor, the more rapidly heat will be transferred. Metal is a good conduction of heat.

Examples :-

  • After a car is turned on, the engine becomes hot. ...
  • A radiator is a good example of conduction. ...
  • You can warm your back muscles with a heating pad.

Convection :-

Thermal energy is transferred from hot places to cold places by convection. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas.

Examples :-

  • Boiling water - The heat passes from the burner into the pot, heating the water at the bottom. ...
  • Radiator - Puts warm air out at the top and draws in cooler air at the bottom.
  • Steaming cup of hot tea - The steam is showing heat being transfered into the air.

Radiation :-

Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object as is the case with conduction and convection.

Examples :-

  • Ultraviolet light from the sun.
  • Heat from a stove burner.
  • Visible light from a candle.
