Nature of meniscus for liquid of 0^o angle of contact is

A liquid wets a solid completely. The meniscus of the liquid in a sufficently long tube is

The excess pressure inside a spherical drop of water is four times that of another drop. Then their respective mass ratio is

A long cylindrical glass vessel has a small hole of radius r at its bottom. The depth to which the vessel can be lowered vertically in the deep water bath (surface tension T) without any water entering inside is

Pressure inside two soap bubbles are 1.01 and 1.02 atmospheres. Ratio between their volume is

When a large bubble rises from the bottom of a lake to the surface, its radius doubles. If atmospheric pressure is equal to that of column of water height H, then the depth of lake is

Excess pressure of one soap bubble is four times more than the other. Then , the ratio of volume of first bubble to another one is

If pressure at half the depth of a lake is equal to 2/3 pressure at the bottom of the lake, then what is the depth of the lake ?

Due to capillary action, a liquid will rise in a tube, if the angle of contact is

Water rises in plant fibres due to
