5 people got tapped in an elevator due to electricty failure generator took 10 mins for being operational. Describe briefly changes in composition of air inside lift

See the answer below

Explanation:

Since no fresh air is coming into the elevator while the people are still trapped in it, the breathing of the people will alter the composition of the air inside the lift.

Breathing involves taking-in of oxygen and the release of carbon dioxide. Hence, less and less oxygen will become available within the lift while the concentration of the carbon dioxide keeps increasing as time goes on.

If the people remain trapped for a long time, the oxygen composition of the air inside the elevator will become exhausted, the carbon dioxide concentration will increase, and the people will suffocate due to lack of oxygen.

the correct answer is answer a. a mixture

no other options make sense

hope this

have a great day : )
