What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object due to their motion and position. It is related to temperature and heat.

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when faster-moving particles collide with slower-moving ones.

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer, less dense fluid rises and cooler, denser fluid sinks.

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light. It does not require a medium to travel through.

How does temperature affect thermal energy?

Back

As temperature increases, the thermal energy of an object also increases because the particles move faster.

What happens to the temperature of two connected rooms over time?

Back

If one room is warmer than the other, heat will transfer from the warmer room to the cooler room until they reach the same temperature.

What is an example of conduction?

Back

An example of conduction is touching a hot stove; heat transfers from the stove to your hand.

Front

What is an example of convection?

Back

An example of convection is boiling water; the hot water rises to the top while cooler water sinks.

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin.
