Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object, related to their motion and position.

Front

How do particles move in a gas?

Back

Particles move independently from one another.

Front

How do particles move in a solid?

Back

Particles vibrate within fixed positions.

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 energy through electromagnetic waves, such as heat from the sun.

Front

What is the state of matter where particles are close together but can slide past each other?

Back

Liquid.

Front

What is the state of matter where particles are tightly packed and vibrate in place?

Back

Solid.

Front

What is the state of matter where particles are far apart and move freely?

Back

Gas.

Front

What happens to particles when thermal energy is added?

Back

They move faster and may change state (e.g., solid to liquid).
