Conduction Convection Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one.

Example of conduction in everyday life?

Back

Heating a kettle on a hot furnace is an example of conduction.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer parts of a fluid rise and cooler parts sink.

Example of convection in everyday life?

Back

Newt boiling in a hot caldron is an example of convection.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium to travel through.

Example of radiation in everyday life?

Back

The warmth felt from the sun is an example of radiation.

Front

How does conduction occur in cooking?

Back

Conduction occurs when food is placed in direct contact with a hot surface, like a pan, transferring heat to the food.

Front

What happens when you touch a hot pan?

Back

When you touch a hot pan, heat is transferred from the pan to your hand through conduction, which can cause a burn.

Front

How does convection work in boiling water?

Back

In boiling water, the water at the bottom heats up, becomes less dense, and rises, while cooler water descends, creating a convection current.

Front

What is an example of convection in the atmosphere?

Back

Warm air rising and cool air sinking in the atmosphere creates wind patterns, which is an example of convection.
