Figure 4 shows a source of heat placed at equal distances from two identical flasks X and Y containing air. The surface of X is painted black while Y is clear
X and Y are linked by a U-tube filled with water whose levels S and T are initially the same.
It is later observed that S falls while T rises. Explain this observation.
