The diagram below shows two flasks of water, one with hot water and the other with room temperature water, which are connected by a conductive metal bar. When initially set up, in which direction does the thermal energy between the flasks flow?

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

Thermal energy flows equally between the two flasks.
Thermal energy flows equally between the two flasks.

Thermal energy flows from the flask on the left to the flask on the right.
Thermal energy flows from the flask on the left to the flask on the right.

Thermal energy flows from the flask on the right to the flask on the left.

Answer 1

In the scenario described, where one flask has hot water and the other has room temperature water connected by a conductive metal bar, thermal energy will flow from the flask with hot water (the flask on the left) to the flask with room temperature water (the flask on the right).

So the correct response is:

Thermal energy flows from the flask on the left to the flask on the right.
