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

What is temperature?

Back

Temperature is the measurement of the average kinetic energy of particles in a substance.

Front

What is a thermal insulator?

Back

A thermal insulator is a material that does not conduct heat well, preventing the transfer of thermal energy.

Front

Give an example of a good thermal insulator.

Back

Styrofoam is a good thermal insulator.

Front

Which has more thermal energy: a small piece of ice or a large iceberg?

Back

The large iceberg has more thermal energy because it has more particles (matter).

Front

What happens to thermal energy when you place an ice cube in hot soup?

Back

Energy is transferred from the soup to the ice cube.

Front

What is the relationship between temperature and thermal energy?

Back

Higher temperature generally indicates higher thermal energy, as the particles are moving faster.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases).

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, such as heat from the sun.
