What is thermal energy?

Back

The motion of atoms or molecules within a substance.

Front

Why do atoms have kinetic energy?

Back

Because they are always vibrating.

Front

What is heat?

Back

The transfer of thermal energy from a hotter area to a colder area.

Front

How does temperature relate to kinetic energy?

Back

Cold things often have a lower kinetic energy because particles are moving around less.

Front

What do we measure temperature with?

Back

Celsius or Fahrenheit degrees.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.

Front

What happens to thermal energy when a substance is heated?

Back

It increases, causing the particles to move faster.

Front

What is the relationship between temperature and thermal energy?

Back

Higher temperature means higher thermal energy.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids and gases).
