Latent heat of vaporization of two liquids a and b is 100 joule/kg and 150 joule/kg respectively which one can produce more cooling effect and why?

Solution
Liquid B can produce more cooling effect, because it has a higher latenet heat of vaporisation( when compared to liquid A) therefore, it absorbs more heat than Liquid A( whose latent heat of vaporisation is 100j/kg).
