Front

What is radiation?

Back

Radiation is the transfer of heat in the form of waves, such as heat from the sun.

Front

What happens to particles when heat is added?

Back

When heat is added, the particles gain energy and move faster, causing the substance to expand.

Front

What is thermal expansion?

Back

Thermal expansion is the increase in volume of a substance as its temperature increases.

Front

What is thermal contraction?

Back

Thermal contraction is the decrease in volume of a substance as its temperature decreases.

Front

What materials are good conductors of heat?

Back

Metals like copper and aluminum are good conductors of heat.

Front

What materials are good insulators of heat?

Back

Materials like wood, plastic, and rubber are good insulators of heat.
