it can be easily reversed because nothing new is produced. it is the same particles but just rearranged. it is just a change in size, shape or state ***IT IS REVERSIBLE*** but what physical change is not easy to reverse?
any measurable quantity
Yes, evaporation of spirit on the skin is a physical change. It is a phase change where the liquid spirit changes into a gas without any chemical reaction occurring. The process can be reversed by condensation.
