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 thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases) caused by differences in temperature.

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as heat from the sun.

How does an air conditioner cool a room?

Back

An air conditioner cools a room by removing heat from the air, causing the air molecules to slow down.

What is the relationship between temperature and molecular motion?

Back

As temperature increases, molecular motion increases; as temperature decreases, molecular motion decreases.
