Q. If a liquid does not wet glass, its angle of contact is:

Explain why

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

(b) 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.)

(d) Water with detergent dissolved in it should have small angles of contact.
