(RETEACH) Unit 4: Thermal Energy & Equilibrium

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two or more objects in contact with each other reach the same temperature, resulting in no net transfer of thermal energy between them.

Front

True or False: When thermal equilibrium occurs, the transfer of energy in the system stops.

Back

True

What is the primary method of heat transfer when a chair gets warm from a fireplace?

Back

Radiation

Front

How does thermal energy move in a closed room with a hot radiator?

Back

Through convection.

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 or gases) caused by differences in temperature and density.

What is radiation?

Back

Radiation is energy that travels as electromagnetic waves or rays through space between objects and materials.

Front

How does thermal energy move within a closed system until thermal equilibrium is reached?

Back

It moves from warmer to cooler areas until equilibrium.

Front

What is the role of insulation in thermal energy transfer?

Back

Insulation reduces the transfer of thermal energy between objects, helping to maintain temperature.

Front

What happens to thermal energy in a system when it reaches equilibrium?

Back

The transfer of thermal energy stops, as all parts of the system are at the same temperature.
