Q. Ability to rise in thin tubes and ability to resist pulling force are respectively :

Q. Ability to rise in thin tubes and ability to resist pulling force are respectively :

(a) Tensile strength and capillarity.

(b) Cohesion and adhesion.

(c) Capillarity and tensile strength.

(d) Adhesion and capillarity.

Solution :

Correct option : C Capillarity is the ability of water to rise through thin tubes. The tensile strength of a substance is how well it can resist external force and maintain it’s properties. Cohesion is the attraction of two same particles. Adhesion is the attraction of two different particles. So the correct answer is ‘Capillarity and tensile strength’.
