Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in an object.

Front

Why do particles in boiling water move faster than in ice water?

Back

Because the particles in boiling water have more thermal energy, causing them to move faster.

Front

What does the Greek prefix 'thermo-' mean?

Back

The Greek prefix 'thermo-' means 'heat'.

Front

How much thermal energy does a large amount of matter need to warm up compared to a small amount?

Back

A large amount of matter needs more thermal energy to warm up than a small amount.

Front

Does mechanical energy create thermal energy?

Back

Yes, mechanical energy can create thermal energy through friction and movement.

Front

What happens to particles when they are heated?

Back

When particles are heated, they begin to move faster.

Front

What is the relationship between temperature and particle movement?

Back

As temperature increases, the movement of particles increases.

Front

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 and gases).

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, such as sunlight.
