A student spilled a bottle of ammonia in one corner of the laboratory. Soon the whole laboratory was filled with pungent irritating smell. The students immediately opened the windows and doors and switched on the exhaust fans. After sometime, students got relief. Explain what did actually happen?

Answer 1

Ammonia is a strong colourless gas.it has strong and irritating smell.it creates irritating atmosphere with its smell.even it is spilled at the corner of room it can diffuse to whole room fastly.so the students felt irritating and unpleasant smell.

Answer 2

Answer: The correct answer is-

Initially when the student spilled ammonia bottle, its gas particles diffused  with the air particles that were present in the room.

Rate of diffusion of gases is very high. Therefore, in the starting the entire room got filled with ammonia, which has a pungent smell.

When students opened the doors and windows and switched on the exhaust fan, the air particles present in the room moved outside through diffusion. At the same time, air present outside the room entered inside.

Due to this, ammonia gas concentration in the room was declined, giving relief to the students.
