"Water stick to the walls of a glass tube, but mercury does not." Why?

Mercury sticks to the walls of the capillary tube.

Water drops stick to a glass surface due to

Water does not wet an oily glass because

Explain why the liquid oxygen sticks to the magnet pole but liquid nitrogen does not ?

When a fluoride is heated with concentration H_(2)SO_(4) in a glass tube and if a drop of water is held at the mouth of the glass tube, a white deposit formed is of

Water rises in a glass capillary tube, but descends if the bore of the capillary tube is coated with paraffin wax. Why ?

Water rises to a height of 10 cm in capillary tube and mercury falls to a depth of 3.112 cm in the same capillary tube. If the density of mercury is 13.6 and the angle of contact for mercury is 135^(@) , the ratio of surface tension of water and mercury is

Water meniscus in a glass tube is concave while that of mercury is convex. Why ?

An open U-tube contains mercury. When 11.2 cm of water is poured into one of the arms of the tube, how high does the mercury rise in the other arm from its initial level ?

Water rises to a height of 10 cm in a capillary tube and mercury falls to a depth of 3.42 cm in the same capillary tube. If the density of mercury is 13.6 g//c.c. and the angles of contact for mercury and for water are 135^@ and 0^@ , respectively, the ratio of surface tension for water and mercury is
