Back

The substance may freeze.

Front

What does temperature measure in a substance?

Back

Temperature measures the average kinetic energy of the atoms in a substance.

Front

In which direction does thermal energy always move?

Back

Thermal energy always moves from a warmer area to a cooler area.

Front

What happens to the temperature when the kinetic energy of molecules in a substance increases?

Back

The temperature increases.

Front

What effect does removing thermal energy have on the vibration of atoms in a substance?

Back

Removing thermal energy causes its atoms to vibrate slower.

Define 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 an object has due to its motion.

Front

What is the relationship between thermal energy and temperature?

Back

As thermal energy increases, the temperature of a substance typically increases.
