Amplify Thermal Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

Do molecules move at the same speed regardless of temperature?

Back

False. Molecules move faster at higher temperatures.

Front

How do energy transfers occur?

Back

Energy transfers occur when molecules collide with each other.

Front

What happens to temperature when heat transfer is complete?

Back

The temperature will equalize to a common value between the two samples.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state reached when two objects at different temperatures come into contact and their temperatures equalize.

Front

What is thermal energy?

Back

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

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the average kinetic energy of the molecules increases.

Front

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves.
