A bag of cement lying in the open gets wet due to rain during the night. The
next day the sun shines brightly. Do you think the changes, which have occurred
in the cement, could be reversed?

Answer:
No the change should not be reversed. Because cement contains silica and many other things which become hards on action with water. So the hardened cement can't be reversed.

Answer:
No, the changes which have occurred in the cement couldn't be reversed. When sunlight falls on the wet cement, chemical changes occur which is a irreversible process.
