Define angle of contact .

Explain why The angle of contact of mercury with glass is obtuse. While that of water with glass is acute .

Explain why (a) The angle of contact of mercury with glass is obtuse , while of water with glass is acute .

The angle of contact between drop of water and material of raincoat is acute angle.

Liquid rises to a height of 2 cm in a capillary tube and the angle of contact between the solid and the liquid is zero. If the tube is depressed more now so that top of capillary is only 1 cm above the liquid, then the apparent angle of contact between the solid and the liquid is

The angle of contact at the interface of water glass is 0^(@) ethylalcohol glass is 0^(@) mercury glass is 140^(@) and methyliodide glass is 30^(@) A glass capillary is put in a trough containing one of these four liquids . It is observed that the meniscus is convex.the liquid in the trough is

Why tefllon is coated ,the angle of contact between oil and non -stick frying pan ?

Radius of a glass capillary is 0.5 mm . Find the height of the column of water when it is held vertical in water . The density of water is 10^(3)kg m^(-3) and the the angle of contact between glass and water is 0^(@),g=9.8ms^(-2) and the surface tension of water T=0.0727Nm^(-1) .

How angle of contact depend on temperature ?

Liquid is stick to the glass then angle of contact for liquid glass will be obtain …..(acute /obtuse)
