Thermal Energy (Amplify)

Front

What happens to energy when two samples come in contact?

Back

Energy flows from the warmer one to the cooler one.

Front

How do energy transfers occur?

Back

Energy transfers occur when molecules collide with each other.

Front

What is the definition of 'average'?

Back

Back

The other object will increase in temperature.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance.

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.

Front

What is equilibrium in thermal energy?

Back

Equilibrium occurs when two objects reach the same temperature and no heat flows between them.
