Heat Transfer
How is heat transferred from one source to another?
There are 3 ways in which heat can be transferred.
There are 3 ways in which heat can be transferred.
- thermal conduction
- thermal convection
- thermal radiation
Thermal conduction occurs when heat energy is transferred from one solid object to another through physical contact.
Heat convection occurs when bulk flow of a fluid (gas or liquid) carries heat along with the flow of matter in the fluid.
Thermal radiation is the transfer of heat energy by means of photons (light rays) or waves of electromagnetic radiation.
