Thermal Energy Test

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance, which is related to its temperature.

Front

What happens to the kinetic energy of atoms when they vibrate?

Back

When atoms vibrate, their kinetic energy increases, leading to an increase in temperature.

Front

What is the relationship between thermal energy and temperature?

Back

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

Front

What occurs during a chemical reaction that releases energy?

Back

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

Front

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

Back

Adding thermal energy to a substance typically causes it to heat up.

Front

What is the effect of removing thermal energy from a substance?

Back

Removing thermal energy from a substance typically causes it to cool down.

Front

True or False: Adding or removing thermal energy can change the state of matter.

Back

False. Adding or removing thermal energy can change the state of matter.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion, which in this context refers to the movement of atoms and molecules.

Front

How does temperature relate to the motion of molecules?

Back

Temperature is a measure of the average kinetic energy of the molecules in a substance.

Front

What happens to the thermal energy of a substance when it freezes?

Back

When a substance freezes, it loses thermal energy, causing its molecules to slow down and arrange into a solid structure.
