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, which can occur in a vacuum.

Why does a dog lay down next to a wood stove?

Back

The dog lays down next to the wood stove to absorb heat through radiation.

Front

What are conductors?

Back

Conductors are materials that allow heat to flow through them easily, such as metals like copper and aluminum.

Front

What are insulators?

Back

Insulators are materials that do not allow heat to flow through them easily, such as plastic and rubber.

Front

What happens to a spoon left on a hot pot?

Back

The spoon becomes hot due to conduction, as heat is transferred from the pot to the spoon.

Front

What is an example of convection in everyday life?

Back

An example of convection is the way warm air rises and cool air sinks 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, even when you are not in direct contact with it.

Front

Which material is NOT a good conductor of heat?

Back

Plastic is not a good conductor of heat; it is an insulator.
