Why water wets glass, but not mercury?

Explain why Water on a clean glass surface tends to spread out while mercury on the same surface tends to form drops. (Put differently, water wets glass while mercury does not.)

Explain why (a) The angle of contact of mercury with glass is QBtuse, while that of water with glass is acutue

Why does a thick glass trembler crack on pouring hot water into it?

A narrow tube of radius 1.0 mm made of glass is dipped in mercury. By what amont does the mercury dip down in the tube relative to the mercury surface outside?

A manometer reads the pressure of a gas in an enclosure as shown in Fig. 10.25 (a) When a pump removes some of the gas, the manometer reads as in Fig. 10.25 (b) The liquid used in the manometers is mercury and the atmospheric pressure is 76 cm of mercury. (a) Give the absolute and gauge pressure of the gas in the enclosure for cases with mercury)

Why does the level of mercury fall in a capillary?

Why do we see water droplets collected on the outer surface of a glass container?
