Science
While cooking, if the bottom of the vessel is getting blackened on the outside, it means that
- the food is not cooked completely
- the fuel is not burning completely
- the fuel is wet
- the fuel is burning completely
Answer
the fuel is not burning completely
Reason — While cooking, if the bottom of the vessel is getting blackened on the outside it means that the fuel is not burning completely because certain substances burn partially due to limited supply of oxygen, producing carbon monoxide and soot. The black mark on the vessel is due to the deposition of soot.
