Question

Give reason.
Latent heat of evaporation of two liquids A and B is 100 J/kg and 150 J/kg respectively. Which one can produce more cooling effect and why?​

Answer 1

Answer:

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 the higher latent heat of evaporation as compared to liquid A.

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