We all think that by increasing the temp of a liquid, the surface tension would reduce and so capillary rise will not be as high. But on increasing the temp, the liquid's density also decreases and so the weight of liquid to be lifted also reduces. Which will have the dominating effect, decrease in the weight of liquid leading to an increase in capillary height or a decrease in the surface tension causing a fall in the capillary height?
