What is temperature

• A form of energy
• a measure of how hot or cold something is

What is heat

• the energy that moves from something hot to something cold
• the measure of how hot something is

Molecules or particles in a hot substance...

• move quickly
• move slowly

Molecules move from

• hot to cold

what is kinetic energy

• energy of something at rest
• energy of something moving

The more molecules move...

• the colder they get
• the hotter they get

What is thermal equilibrium

• When energy transfers from hot to cold until both objects reach the same temperature
• When all the cold molecules move to the hot molecules

What is specific heat?

• The energy needed to heat up a material
• The rate at which things would start on fire

Which heats up faster?

• plastic
• metal
