Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in an object.

Front

What is the direction of thermal energy movement?

Back

Thermal energy always moves from a hotter area to a colder area.

Front

What is the boiling point of water?

Back

The boiling point of water is 100°C or higher.

Front

What is a thermos?

Back

A thermos is a container that keeps liquids hot or cold by using insulation.

Front

Why do thermoses use a vacuum?

Back

Thermoses use a vacuum to prevent air molecules from transferring thermal energy.

Front

What happens to matter when thermal energy is added?

Back

When thermal energy is added, matter can change state, such as from solid to liquid.

Front

What happens to matter when thermal energy is removed?

Back

When thermal energy is removed, matter can change state, such as from gas to liquid.

Front

What is steam?

Back

Steam is water vapor that exists at 100°C or higher.

Front

How does popcorn pop?

Back

Popcorn pops when microwaves increase the thermal energy of the water molecules inside the kernels.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.
