Question

Latent heat of vapourisation of two liquids A and B are 100Jkg-1 and 175Jkg-1. It was observed that B causes more cooling while A evaporates faster and is more volatile. Also which out of the two liquids will have a lower boiling point and why?

Answer 1

A has lower boiling point bcoz less latent heat of vapourization is required for it to vapourize
