Question

practice it!
the diagram shows the small container of water inside a larger container of water.
select the statement(s) that accurately describe what is happening in the diagram.
radiation is heating up the smaller container from the air touching the water.
the thermal energy is flowing from the hot substance to the cold substance.
the thermal energy is flowing from the cold substance to the hot substance.
conduction is transferring heat from one container to the other.
eventually, both containers will have water that is the same temperature.

Explanation:

1. Analyze each statement:

• "Radiation is heating up the smaller container from the air touching the water": Radiation is transfer via electromagnetic waves, while heat from air touching water is convection or conduction, so this is incorrect.
• "The thermal energy is flowing from the hot substance to the cold substance": By the second law of thermodynamics, heat (thermal energy) flows from hot to cold, so this is correct.
• "The thermal energy is flowing from the cold substance to the hot substance": This violates the second law of thermodynamics, so incorrect.
• "Conduction is transferring heat from one container to the other": If the containers are in contact or the water is in a setup where heat can conduct (e.g., containers are conductive), heat can transfer via conduction between them, so this can be correct.
• "Eventually, both containers will have water that is the same temperature": This is thermal equilibrium, which occurs when heat transfer stops, so this is correct.

Answer:

The accurate statements are:

• The thermal energy is flowing from the hot substance to the cold substance.
• Conduction is transferring heat from one container to the other.
• Eventually, both containers will have water that is the same temperature.
