Insulators, Conductors, Expansion, and Contraction

Front

What happens to the temperature if the atoms of an object are moving or vibrating fast?

Back

The temperature would be hot.

Front

What is a conductor?

Back

A conductor is a material that allows heat to pass through.

Front

What is an insulator?

Back

An insulator is a material that stops heat from passing through.

Front

Which of the following is NOT an insulator: Wool, Plastic, Iron, Glass?

Back

Iron is NOT an insulator.

Front

What happens to the liquid in a thermometer when it is placed in hot water?

Back

The liquid rises because it gains heat from the hot water and expands.

Front

Give an example of a good conductor of heat.

Back

Copper is a good conductor of heat.

Front

Give an example of a good insulator of heat.

Back

Wool is a good insulator of heat.

Front

What is thermal expansion?

Back

Thermal expansion is the increase in volume of a substance when it is heated.

Front

What is thermal contraction?

Back

Thermal contraction is the decrease in volume of a substance when it is cooled.

Front

How does temperature affect the movement of atoms in a substance?

Back

As temperature increases, atoms move or vibrate faster.
