Conduction
Conduction is the process by which heat energy is transferred through direct contact between objects.
- Examples of conduction include heating a cup of coffee near a radiator, or feeling cold air on your skin.
- The rate of convection depends on the temperature difference and the surface area in contact with the heat source or sink.
Convection
Convection is the transfer of heat through the movement of fluids. It occurs when a fluid (liquid or gas) is heated, causing it to expand and rise.
Natural convection occurs in nature, such as in ocean currents or chimney smoke.
Radiation
Radiation is the transfer of heat energy through electromagnetic waves. It can occur through open flames, incandescent bulbs, or even the sun's rays.
There are two types of radiation: thermal radiation (heat) and non-thermal radiation (other forms of radiation).
