Solution
The correct option is A Physical When a cold water bottle is taken out from the refrigerator, the water vapour in the air around the bottle comes in contact with the cold surface of the bottle and gets condensed. So there is a change in state of water from gas to liquid. There is no change in chemical composition of water and no new product is formed. Therefore, the change involved is physical.
