What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in an object. It is related to temperature and the amount of substance.

What does kinetic energy refer to?

Back

Kinetic energy is the energy an object possesses due to its motion. The faster an object moves, the more kinetic energy it has.

How does heat transfer occur between two objects?

Back

Heat transfer occurs from the hotter object to the cooler object until they reach thermal equilibrium.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What happens to the temperature of an object when it gains thermal energy?

Back

When an object gains thermal energy, its temperature increases as the kinetic energy of its particles increases.

What is the relationship between temperature and average kinetic energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance; higher temperatures indicate higher average kinetic energy.

What is conduction?

Back

Conduction is the process of heat transfer through direct contact between materials, where energy is transferred from the hotter to the cooler object.

What is the formula for calculating average kinetic energy?

Back

Average kinetic energy (KE) can be calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

What is the significance of the number of molecules in thermal energy?

Back

The number of molecules affects the total thermal energy of an object; more molecules can store more energy.

What occurs when two objects at different temperatures touch each other?

Back

When two objects at different temperatures touch, heat flows from the hotter object to the cooler one until they reach the same temperature.
