Two liquids of different temperatures are separated by a non-heat conducting barrier. The hot liquid is on the right side, and the cold one is on the left side.

Which statement best describes how the molecules move in heat flow?

Responses

Molecules from the right collide and transfer heat to the barrier, which transfers heat to the left side.


Molecules from the left collide and transfer heat to the barrier, which transfers heat to the right side.


Molecules from the right collide and transfer heat directly to the right side.


Molecules collide but do not transfer heat to the left side.
