Two narrow bores of diameters 3.0 mm and 6.0 mm are joined together to form a U-tube open at both ends. If the U-tube contains water, what is the difference in its levels in the two limbs of the tube ? Surface tension of water at the temperature of the experiment is `7.3 × 10^(–2)` N `m^(–1)`. Take the angle of contact to be zero and density of water to be `1.0 × 10^3` kg `m^(–3)` (g = 9.8 m
Mercury has an angle of contact equal to 140° with soda lime glass. A narrow tube of radius 1.00 mm made of this glass is dipped in a trough containing mercury. By what amount does the mercury dip down in the tube relative to the liquid surface outside ? Surface tension of mercury at the temperature of the experiment is 0.465 N `m^(–1)`. Density of mercury = `13.6 × 10^3` kg
Explain why The angle of contact of mercury with glass is obtuse, while that of water with glass is
