Thermal Energy Review

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

How does the number of particles in a substance affect its thermal energy?

Back

The more particles a substance has at a given temperature, the more thermal energy it has.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials without the movement of matter.

Front

What is convection?

Back

Convection is the transfer of heat by the movement of fluids (liquids or gases) due to differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, which can occur in a vacuum.

Front

What is an example of conduction?

Back

An example of conduction is when a metal spoon becomes warm after being placed in a hot bowl of soup.

Front

What is an example of convection?

Back

An example of convection is the warm air rising and cool air sinking in a room heated by a radiator.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin.

Front

What happens to the temperature of a block that absorbs more light?

Back

The block that absorbs more light will increase in temperature more rapidly.

Front

What is the relationship between temperature and thermal energy?

Back

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