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 is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.

Front

When does heat transfer stop?

Back

Heat transfer stops when two objects reach thermal equilibrium, meaning they are at the same temperature.

Front

What happens to molecular motion when temperature decreases?

Back

When temperature decreases, the molecules move slower.

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 temperature increases, the average kinetic energy of the particles in a substance also increases.

Front

What is conduction?

Back

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

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.
