Thermal Energy Flashcard

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in a substance.

Front

How can you feel thermal energy?

Back

You can feel thermal energy by feeling the warmth of the sun or any hot object.

Front

What is conduction?

Back

Conduction is the flow of thermal energy through direct contact between materials.

Front

Give an example of conduction.

Back

An example of conduction is placing a pot on a hot stove.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as sunlight.

Front

How does thermal energy transfer through radiation?

Back

Thermal energy transfers through radiation without needing a medium, allowing it to travel through space.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases).

Front

Give an example of convection.

Back

An example of convection is warm air rising and cool air sinking in a room.

Front

What is the difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids.

Front

What materials are good conductors of thermal energy?

Back

Metals like copper and aluminum are good conductors of thermal energy.
