  1. When wood burns, the carbon present in it is oxidised to carbon dioxide (CO2), which is a non-poisonous gas. When the windows are closed, fresh air or oxygen cannot enter the room. Due to the insufficient supply of oxygen, carbon is oxidised to carbon monoxide (CO2), which is a highly poisonous gas. It causes suffocation in a closed room. On opening the windows, the poisonous gas slowly diffused out of the room and fresh air came inside due to which the feeling of suffocation reduced gradually.
  2. Mohan is quite intelligent, quick in decisions and caring about his family.
