The parts of motor cars are polished by chromium because the angle of contact between water and chromium is

$A$ liquid does not wet the sides of a solid,if the angle of contact is

Given below are two statements:
Statement-$I$: When a capillary tube is dipped into a liquid,the liquid neither rises nor falls in the capillary. The contact angle may be $0^{\circ}$.
Statement-$II$: The contact angle between a solid and a liquid is a property of the material of the solid and liquid as well.
In the light of the above statements,choose the correct answer from the options given below.

If a liquid wets a surface,is its angle of contact acute or obtuse?

Define the angle of contact.

$A$ capillary tube is dipped vertically in a liquid. If the liquid surface is hemispherical,then the angle of contact $\theta$ is
