Front

What is convection?

Back

A transfer of heat within a liquid or gas that involves warm particles moving in currents.

What happens to warm air in a room?

Back

Warm air rises due to convection.

Front

Give an example of convection in everyday life.

Back

Boiling water where warm water rises and cool water sinks.

Front

What is an example of conduction?

Back

Touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of radiation?

Back

How does convection affect weather patterns?

Back

Warm air rises, creating low pressure areas that can lead to wind and storms.

Front

What is the role of conduction in cooking?

Back

Heat transfers from the stove to the pot and then to the food.
