Charcoal burns more strongly in pure oxygen than in normal air because oxygen is a key component in the combustion process. When charcoal is burned in normal air, it is only able to access the limited amount of oxygen present in the air, which slows down the combustion process. However, when charcoal is burned in pure oxygen, it has access to a higher concentration of oxygen, allowing for a more efficient and intense combustion reaction. This results in a stronger and more rapid burn. **
