Question

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

Answer 1

Correct Option is (B)

Step-by-step explanation:

Work of cohesion per unit surface is equal to 2
`\gamma`.

where
`\gamma` 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
`W_(c)`.

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