Latest heat of vaporisation of two liqui...

Latest heat of vaporisation of two liquids A and B are `100 J//kg " and" 150 J//kg` respectively. Which one can produce more cooling effect ?

Text Solution

Verified by Experts

The liquid B can cause more cooling effect than the liquid A because it absorbs more heat from the surrounding during the change of state from liquid to the vapours.
