1.	What will happen if heating is not controlled while preparing Plaster of Paris from gypsum?
Answer» It may be noted that the temperature should be controlled carefully. It should not be allowed to rise above 152°C (425K) because, if whole of the water is lost then anhydrous calcium sulphate is produced, which is called dead burnt plaster and it does not have the properties of Plaster of Paris.
