Front

What is convection?

Back

Convection is the transfer of thermal (heat) energy through liquids and gases, where hotter particles rise and cooler particles sink.

What is the main difference between conduction and convection?

Back

Conduction occurs in solids through direct contact, while convection occurs in liquids and gases through the movement of particles.

Front

Can radiation occur in a vacuum?

Back

Yes, radiation can occur in a vacuum because it does not require a medium to transfer energy.
