Temperature Distribution from 550 to 310 C. During the cool down process, heat losses to the environment o er enough buoyancy forces to drive the molten salt to natural convection, with the result that the molten salt near the tank walls cools down. Thus, its density increases and moves down to the bottom of the tank.
