Thermal Energy

Front

What is thermal energy?

Back

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

Front

How does the mass of an object affect its thermal energy?

Back

Objects with more mass have more thermal energy because there are more molecules moving.

Front

What happens to water when it freezes?

Back

When water freezes, it changes from a liquid to a solid.

Front

What is the process called when a liquid turns into a gas?

Back

The process is called evaporation.

Front

What is an insulator?

Back

An insulator is a material that reduces the transfer of thermal energy.

Front

What happens to the temperature of an object if an insulator is effective?

Back

The temperature of the object should show very little change over time.

Front

What is the difference between boiling and evaporation?

Back

Boiling occurs at a specific temperature throughout the liquid, while evaporation can occur at any temperature.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion, which increases as the temperature of a substance increases.

Front

What is the relationship between temperature and thermal energy?

Back

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

Front

What is melting?

Back

Melting is the process where a solid changes into a liquid.
