Intro to Thermal Energy

Front

What happens to the atoms of a substance when thermal energy is removed?

Back

The atoms vibrate slower.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

What type of chemical reaction can be used to heat up other substances?

Back

A chemical reaction that releases energy.

Front

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

Back

The temperature increases.

Front

What does temperature measure in a substance?

Back

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

Front

What is thermal energy?

Back

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

Front

How does thermal energy relate to temperature?

Back

Thermal energy affects the temperature; more thermal energy usually means a higher temperature.

Front

What is the relationship between kinetic energy and temperature?

Back

As kinetic energy increases, temperature increases.

Front

What happens to the motion of atoms when a substance is heated?

Back

The atoms vibrate faster.

Front

What is the effect of adding thermal energy to a substance?

Back

It increases the kinetic energy of the atoms.
