Why does plaster of paris harden on mixing with water?
Asked by Lanzmik | 11 Nov, 2020, 10:35: PM
Expert Answer
Making statues out of plaster of Paris is an irreversible change because plaster of Paris has a property of setting into a hard mass on getting mixed with water due to the formation of a new compound. The hard mass cannot be converted back into the previous plaster of Paris. Hence, it is an irreversible change.
