Conduction vs Convection vs Radiation

what’s conduction and why does it occur?

conduction is the transfer of heat energy when two objects are in physical contact. It occurs because the vibration of particles in the hotter object is passed along to the cooler object.

Give an example of conduction.

metal spoon in tea, ice cubes placed on metal surfaces

What is convection?

the transfer of heat energy through the movement of heated fluids.

Provide examples of convection

boiling water, using air conditioners

What is natural convection?

result from the tendency of most fluids to expand when heated. (become less dense and to rise as a result of the increased buoyancy.)

What is a heat pump? Provide an example.

A device that takes heat from one area and pumps it to another e.x: refrigerator

What is radiation?

the transfer of heat energy by means of electro-magnetic waves (light, x-rays, microwaves)
