Question

which has higher rate of evaporation-

(A) nail-paint remover

(B) alcohol

Answer 1

The liquid which has lower boiling point will have a higher rate of evaporation, as lower is the boiling point of a liquid then easier it is for the substance to escape into the vapour phase. Nail paint remover is acetone, whose boiling point is 56⁰ C. On the other hand, the boiling point of simplest alcohol that is methanol is 64.7⁰ C while that of ethanol is 78.4⁰ C. So, because the boiling point of acetone is lower than the two of the simplest alcohols, it has a higher rate of evaporation
