Thermal Energy

Front

What does temperature measure in terms of molecular movement?

Back

Temperature measures the average movement of molecules.

Front

What happens to molecules as temperature increases?

Back

Molecules move faster.

Front

What happens to the temperature of a substance if the kinetic energy of its atoms/molecules increases?

Back

The temperature increases.

Front

What is the kinetic energy of cold things compared to warmer things?

Back

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

Front

How do we describe energy in terms of temperature?

Back

Temperature is a way we measure energy.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in a substance.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

How does thermal energy relate to temperature?

Back

Higher thermal energy usually means a higher temperature.

Front

What happens to the speed of particles in a substance when it is heated?

Back

The speed of particles increases.

Front

What is the relationship between temperature and molecular motion?

Back

As temperature increases, molecular motion increases.
