Thermal Energy Review

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in a substance, which is related to its temperature.

What happens to light when it reflects off a surface?

Back

When light reflects off a surface, it bounces back instead of being absorbed or transmitted.

Front

What is temperature a measure of?

Back

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

Front

What occurs when two marbles collide?

Back

When two marbles collide, energy is transferred; the faster marble slows down while the slower marble speeds up.

Front

What is Joule's Experiment?

Back

Joule's Experiment demonstrates how mechanical energy can be converted into thermal energy, showing that spinning paddles in water can increase its temperature.

Front

What is the difference between reflection and transmission of light?

Back

Reflection is when light bounces off a surface, while transmission is when light passes through a material.

Front

What is an example of a material that reflects but does not transmit light?

Back

Aluminum is an example of a material that reflects light but does not transmit it.

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object or system to another.

Front

How does thermal energy relate to temperature?

Back

Thermal energy is the total energy of all particles in a substance, while temperature is the average energy of those particles.

Front

What is the role of kinetic energy in thermal energy?

Back

Kinetic energy contributes to thermal energy as it is the energy of motion of the particles in a substance.
