In a surface tension experiment, the lower end of a capillary tube of radius r is placed vertically in water. It is observed that with rise in water heat is evolved. When liquid rises to a height of 2 cm, the angle of contact is zero. If the tube is depressed more now so that the top of the capillary is only 1 cm above the liquid, the angle of contact changes. If the same experiment is repeated in an artificial satellite, still water rises. If water rises to height h, the heat evolved is? ( d is the density of water)
