What is thermal energy?

Back

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

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

How does the thermal energy of a gallon of ice water compare to that of a cup of ice water?

Back

A gallon of ice water has more thermal energy than a cup of ice water.

Front

What happens to the particles of a gas compared to those in a liquid or solid state?

Back

The particles of a gas move faster than the particles of the same substance in the liquid or solid state.

Front

What is the relationship between temperature and thermal energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance, while thermal energy is the total energy of all the particles.

Front

What is the difference between heat and thermal energy?

Back

Heat is the transfer of thermal energy from one object to another, while thermal energy is the energy contained within an object.

Front

What is an example of conduction?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What materials are good conductors of heat?

Back

Metals, such as copper and aluminum, are good conductors of heat.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well, such as wood or plastic.
