Intro to Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the kinetic energy of atoms and molecules in matter.

Front

What type of energy is associated with the motion of atoms and molecules?

Back

Kinetic energy.

Front

What does temperature measure in a substance?

Back

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

Front

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

Back

The temperature increases.

Front

What type of chemical reaction releases energy?

Back

A chemical reaction that releases energy can be used to heat up other substances.

Front

What is the relationship between kinetic energy and temperature?

Back

As kinetic energy increases, temperature also increases.
