Is a hot air popcorn popper and example of convection?

Answer 1

Yes, convection is heating a substance by moving a heated substance against it.

There are 3 types of heating: conduction, convection, and radiation.

Conduction is the transfer of heat by contact, convection is the transfer of heat by mixing a heated substance with a cooler substance, and radiation is the transfer of radiant heat from a distance (no physical contact between substances).

Hope this helps!
