Why liquid ammonia bottle is cooled before opening the seal ?

Text Solution

Verified by Experts

Liquid ammonia bottle contains the gas under high pressure. If we open the bottle without cooling, it may brust due to sudden decrease in the pressure. If bottle is cooled for sometime, the volume of gas inside the bottle decreases to a large extent. If the seal is opened now, the gas comes out slowly reducing the chances of accident.
