Thermal energy does not flow between the two flasks.
Thermal energy does not flow between the two flasks.

Thermal energy flows from the flask with room temperature water to the flask with hot water.
Thermal energy flows from the flask with room temperature water to the flask with hot water.

Thermal energy flows from the flask with hot water to the flask with room temperature water.
Thermal energy flows from the flask with hot water to the flask with room temperature water.

Thermal energy flows equally between the two flasks.

Answer 1

Thermal energy flows from the flask with hot water to the flask with room temperature water. This is due to the second law of thermodynamics, which states that heat energy will naturally flow from a region of higher temperature to a region of lower temperature until thermal equilibrium is reached. Therefore, the correct response is:

Thermal energy flows from the flask with hot water to the flask with room temperature water.
