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 is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, which depends on its mass and velocity.

How does temperature affect kinetic energy?

Back

As temperature increases, the average kinetic energy of the particles in a substance also increases.

What happens to gas particles when temperature decreases?

Back

Gas particles move more slowly because decreasing temperature causes them to have less kinetic energy.

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact no longer transfer thermal energy to each other, resulting in the same temperature.

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 and density.

What is the relationship between mass and thermal energy?

Back

The thermal energy of a substance increases with its mass, as more particles contribute to the total kinetic energy.

What is the effect of adding ice to water on kinetic energy?

Back

Adding ice to water decreases the average kinetic energy of the water particles, as the ice absorbs thermal energy.
