Question

A bottle of liquor ammonia should be opened very carefully, only after cooling it in ice because:

• A. There is a low pressure inside the bottle.
• B. There is a high pressure inside the bottle.
• C. On cooling, the pressure inside the bottle increases.
• D. It’s not necessary to open the bottle of liquor ammonia carefully.

Answer 1

The correct option is B

There is a high pressure inside the bottle.

A bottle of liquor ammonia should be opened very carefully, only after cooling it in ice or cold water. There is a high pressure inside the bottle of ammonia and on cooling, the pressure drops. This prevents sudden flushing out of the gas.
