Question

On a winter night Nishant burnt some wood in his closed room and slept. He started feeling very suffocated in the mid night and ran to open the doors. After moving outside he was relieved. What is the reason behind this?

• A. Because of mixing of other gases
• B. Because of the smell of burnt wood
• C. Because of the incomplete combustion
• D. None of these

Answer 1

The correct option is C

Because of the incomplete combustion

We should not sleep in a closed room when wood or anything is being burnt in the room because there is limited availability of oxygen in a closed room. After consumption of the available oxygen, incomplete combustion of the fuel takes place which gives carbon monoxide gas which is very dangerous for health.
