Answer:
The comparison is between Fuel canister (diethylene glycol) or Tea candle (paraffin)
The answer is tea candle( paraffin)
Explanation:
A fuel’s efficiency is based on its reaction with air(oxygen). It is said to be efficient when it burns well when exposed to air(oxygen).
Tea candle( paraffin) burns more efficiently in the presence of oxygen when compared to fuel canister( diethylene glycol) due to the hydrogen bonds in the molecules of fuel canister( diethylene glycol) making it more stable and having a lesser affinity to air (oxygen) than those of tea candle (paraffin).
