What is thermal energy?

Back

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

Front

What is temperature?

Back

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

Front

How is thermal energy transferred between substances?

Back

Thermal energy is transferred between substances only when they have different temperatures.

Front

What is convection?

Back

Convection is the primary way heat travels through liquids and gases.

Front

What is conduction?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves.

Front

What happens to the temperature of a substance when it absorbs thermal energy?

Back

The temperature of the substance increases as it absorbs thermal energy.

Front

What happens to the temperature of a substance when it loses thermal energy?

Back

The temperature of the substance decreases as it loses thermal energy.

Front

What is the relationship between thermal energy and temperature?

Back

Thermal energy is the total energy of all particles, while temperature is the average energy of the particles.

Front

What is an example of convection in everyday life?

Back

An example of convection is boiling water in a pot, where hot water rises and cooler water sinks.
