Conduction, convection, radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, and does not require a medium.

Front

What happens to thermal energy when hot and cold water are mixed?

Back

Heat (thermal) energy from the hot water is transferred to the cold water until they reach the same temperature.

Front

How does heat move between objects?

Back

Heat moves from warmer objects to cooler objects.

Front

What is an insulator?

Back

An insulator is a material that is a poor conductor of heat, meaning it does not allow heat to pass through easily.

Front

What is a conductor?

Back

A conductor is a material that allows heat to pass through easily, facilitating the transfer of thermal energy.

Front

What is an example of conduction?

Back

An example of conduction is when you touch a hot stove and heat transfers from the stove to your hand.

Front

What is an example of convection?

Back

An example of convection is when hot air rises and cool air sinks, creating a circulation pattern in a room.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin, even though the air around you may be cool.
