Conduction is the transfer of heat through direct contact between solid objects.

Front

Why is the handle of a frying pan often coated in rubber?

Back

Rubber provides heat insulation, preventing the handle from getting too hot.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin.

Front

What happens to the temperature of a cooler object when it comes into contact with a warmer object?

Back

The cooler object absorbs heat and its temperature increases.

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking in a room.

Front

What is the main difference between conduction and convection?

Back

Conduction occurs in solids through direct contact, while convection occurs in fluids through movement.

Front

What is an example of conduction?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.
