Heat transfer

Front

What is a conductor?

Back

A conductor is a material that transfers thermal energy well, allowing heat to flow through it easily.

Front

What is an insulator?

Back

An insulator is a material that does not transfer thermal energy well, preventing heat from flowing through it.

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of thermal energy through space in the form of electromagnetic waves.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

How does the Sun warm the Earth?

Back

The Sun warms the Earth primarily through radiation.

Front

What happens to vinyl siding in a house fire next door?

Back

The vinyl siding warps due to radiation from the heat of the fire.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a pot of boiling water.

Front

What is an example of convection?

Back

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

Front

What is an example of radiation?

Back

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