What is thermal energy?

Back

Thermal energy is the energy that comes from the motion of atoms and molecules. The faster they move, the more thermal energy they have.

How is thermal energy created?

Back

Thermal energy is created by the motion of atoms and molecules.

What is the relationship between thermal energy and temperature?

Back

Thermal energy and temperature are related, but they are not the same. Temperature measures the average kinetic energy of particles, while thermal energy is the total energy of all particles.

What is convection?

Back

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