Question

latent heat of evaporation of two liquids A and B is 100J/kg and 150J/kg respectively. which one can produce more cooling effect and why?

Answer 1

Since we know that, the more the latent heat of evaporation of a liquid, the more cooling effect it produces.

The liquid B will produce more cooling effect because it has a higher latent heat of vapourization as compared to liquid A.

Therefore, the liquid B will absorb more heat and produce a more cooling effect than the liquid A.

Answer 2

Answer:

Liquid B will produce more cooling effect than liquid A, because it will absorb more heat from surroundings for evaporation. (latent heat of evaporation)
