Question

6. On a cold winter night, Hari slept in a closed room with a fire place on and all the
windows closed. What could have happen and why?​

Answer 1

On combustion or burning, carbon dioxide is released. Since hari is sleeping in a closed room, there is no air ventilation and thus no oxygen can enter and no carbon dioxide can be released. After some time, the whole room will become full of carbon dioxide and he will not be able to breathe because no oxygen is entering. Therefore, there are chances of his dying.
