How is heat transferred?

Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. The better the conductor, the more rapidly heat will be transferred. Metal is a good conduction of heat. Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more.

Convection: The transfer of heat by the movement of a fluid (liquid or gas) between areas of different temperature. Warm air is less dense than cold air, and so convection currents can form in the presence of a temperature gradient.

Conduction: The transfer of energy, such as heat or an electric charge, through a substance. In heat conduction, energy is transferred from molecule to molecule by direct contact.

Radiation: The emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes: electromagnetic radiation, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ)
