Question

Vaporisation of alcohol is physical change

Answer 1

#Hello Mate#

Answer:-

Physical. Think of it this way: alcohol(l) --> alcohol(g). When alcohol in liquid form evaporates, it becomes alcohol gas. The gas molecules are the same as the liquid molecules, therefore it is a physical change.

A chemical change involves changing the chemical and molecular composition of alcohol. In this scenario, there is no change in chemical composition of alcohol, just its state of matter.
