Thermal Energy Transfer Review

Front

What is thermal contraction?

Back

Thermal contraction is the process where an object decreases in temperature, causing its particles to slow down and move closer together.

Front

What is thermal expansion?

Back

Thermal expansion is the process where an object increases in temperature, causing its particles to speed up and move further apart.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature, resulting in no net heat transfer between them.

Front

What is conduction?

Back

Conduction is the transfer of heat energy 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 energy through electromagnetic waves, which can occur in a vacuum.

Front

How does temperature affect particle movement?

Back

As temperature increases, particles move faster and spread apart; as temperature decreases, particles slow down and come closer together.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in a sample of matter, related to their temperature.

Front

What happens to heat transfer when two objects reach the same temperature?

Back

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

Front

What is the average kinetic energy of particles in hot tea compared to iced tea?

Back

The average kinetic energy of particles in hot tea is higher than that in iced tea.
