Categorize each statement below as an example of conduction (CD), convection (CV), or radiation (R).

Convection can only occur in solid substances

Conduction commonly occurs in solids such as metal because metal is a good conductor. 

Radiation is a type of heat transfer that can be felt, but not seen since it occurs through electromagnetic waves.

Conduction can occur between any two materials, even if they are not touching.

The movement of warm air in a room is due to radiation

If you place a cup of hot coffee on the counter, it will decrease in temperature until it reaches room temperature. This is called thermal equilibrium

Convection does not occur in solids because the particles of solids are too tightly packed. 

Radiation requires matter in order to transfer heat

Place each of the following characteristics of conduction, convection, and radiation into the correct category.
