Work of cohesion per unit surface is equal to: a) y b) 2y c) (dg/dt)p, t, v d) exp (-ag/rt) e) -sdt-vdp

Correct Option is (B)

Explanation:

Work of cohesion per unit surface is equal to 2.

where is the interfacial energy.

Work of cohesion is the surface free energy which is generated when a column of a pure liquid is divided into two equal parts.

Work of cohesion is reperented by .

Lesser the magnitude of work of cohesion, more will be the spreading of the liquid.
