The value of contact angle for kerosene with solid surface.

Assertion: Pressure on the concave side of the liquid will be greater than pressure on the convex side if the liquid surface is curved. Reason: Excess pressure depends on the angle of contact of the liquid surface with the solid surface.

The angle of contact for a liquid which wets the surface of a solid is

The angle of contact for a liquid which wets the surface of a solid is

does angle of contact depends on the inclination of the solid surface to the liquid surface.

The value of the angle of contact for pure water and mercury with the surface of glass respectively-

Assertion : The angle of contact of a lilquid with a solid decreases with increase in temperature. Reason : With increase in temperature, the surface tension of the liquid increases.

Assertion : The angle of contact of a lilquid with a solid decreases with increase in temperature. Reason : With increase in temperature, the surface tension of the liquid increases.

A liquid does not wet a solid surface if the angle of contact for the given pair of liquid and solid surfaces is

A hydrophilic surface is characterised by the contact angle at the water soled interface. The value of contact angle should be

What will be angle of contact of a liquid relative to solid, if forces of adhesion and cohension are equal?
