Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light or infrared radiation. An example is the sun warming the Earth.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. For example, when a pot is placed on a hot stove, heat is conducted from the stove to the pot.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). For example, warm air rising in a hot air balloon is an example of convection.

Front

How does the sun warm a swimming pool?

Back

The sun warms a swimming pool through radiation, as the sun's rays directly heat the water.

Front

What happens when you place a warm object on a cooler surface?

Back

The warm object transfers heat to the cooler surface through conduction, causing the cooler surface to become warm.

Front

How do marshmallows cook over a fire without touching it?

Back

Marshmallows cook over a fire through radiation, as the heat from the fire radiates to the marshmallows.

Front

What is an example of convection in everyday life?

Back

An example of convection is when hot air rises and cool air sinks, creating a cycle that can be seen in a hot air balloon.

Front

Why does warm air rise?

Back

Warm air rises because it is less dense than cooler air, causing it to expand and rise.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids.

Front

What is an example of conduction in cooking?

Back

An example of conduction in cooking is when a metal spoon gets hot after being placed in a pot of boiling water.
