Sep 18, 2022 · Learn the definitions, examples, and equations of the three types of heat transfer: conduction, convection, and radiation. Also, explore other processes that involve heat, such as chemical bonds and phase transitions.
There are three forms of thermal energy transfer: conduction, convection, and radiation. Conduction involves molecules transferring kinetic energy to one another through collisions. Convection occurs when hot air rises, allowing cooler air to come in and be heated.

- In the process of conduction, heat transfer takes place between objects by direct contact.
- Heat transfer in radiation is the fastest.
- No, conduction does not follow the law of reflection and refraction.
- It is the mode of heat transfer where the heat transfer takes within the fluid.
- It is an example of the radiation mode of heat transfer.
Learn how heat is transferred between objects by direct contact, fluid motion or electromagnetic waves. Compare the key features, examples and laws of conduction, convection and radiation with a comparison chart.
Learn about the three modes of heat transfer: conduction, convection and radiation. Conduction is the transfer of heat by direct contact, convection is the transfer of heat by moving fluid, and radiation is the transfer of heat by electromagnetic waves.
