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

What happens to the temperature of a substance when its molecules speed up?

Back

The temperature of the substance increases.

Front

How does energy flow between two objects at different temperatures?

Back

Energy flows from the warmer object to the cooler object.

Front

What is the definition of 'transfer' in the context of energy?

Back

Transfer refers to the movement of energy from one object to another or from one place to another.

Front

What is kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion.

Front

What is the relationship between temperature and kinetic energy?

Back

As the temperature of a substance increases, the average kinetic energy of its molecules also increases.

Front

What is the definition of 'conduction'?

Back

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

Front

What is the definition of 'convection'?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is the definition of 'radiation'?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light or heat.
