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

Answer 1

When initially set up, thermal energy will flow from the flask with hot water to the flask with room temperature water. This is because heat naturally transfers from a region of higher temperature to a region of lower temperature until thermal equilibrium is reached. The conductive metal bar facilitates this heat transfer between the two flasks.
