Question

Assume that a drop of liquid evaporates by decrease in its surface energy, so that its temperature remains
unchanged. What should be the minimum radius of the drop for this to be possible ? The surface tension is T.
density of liquid is p and L is its latent heat of vaporization
(A)PLIT
(B) T/PL
(C) TipL
(D) 2T/PL​

Answer 1

Answer:

the surface tension is t ans is : 2t/pl
