What does thermal expansion mean?
Measure of the average kinetic energy of the particles in a system.
Energy that flows from a substance of higher temperature to a substance of lower temperature.
When the temperature of a substance is increased, its molecules or atoms jiggle faster and move further apart.
When two different objects end up being balanced.
What are the 3 types of heat energy called. Select all that apply.
Convection
Water
Radiation
Conduction
When a cup of water is affected by a cooler object such as a freezer, what happens to the molecules inside the cup of water?
The molecules speed up and move further apart from each other.
The molecules do not move at all.
The molecules will start to move very slow and end up turning into ice.
The molecules will stay the same.

What happens to telephone wires in the summer?
They contract and become smaller.
They melt because of how hot the temperature is.
Nothing happens.
They become longer and expand more due to thermal expansion.
