Thermal Energy Practice

Front

What does thermal energy depend on?

Back

Thermal energy depends on mass and motion.

Front

What is the average kinetic energy of particles in a substance?

Back

Temperature.

Front

In which direction does heat always move?

Back

Heat always moves from warm areas to cold areas.

Front

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

Back

Thermal energy increases.

Front

What is the flow of thermal energy called?

Back

Heat.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in a substance.

Front

What is the difference between heat and temperature?

Back

Heat is the transfer of thermal energy, while temperature is the measure of the average kinetic energy of particles.

Front

What happens to the particles in a substance when it is heated?

Back

The particles move faster and spread apart.

Front

What is absolute zero?

Back

Absolute zero is the theoretical temperature at which all particle motion stops, equivalent to -273.15°C.

Front

What is conduction?

Back

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