Question

Why is LPG considered a better fuel than coal?

Solution

 Liquefied petroleum gas (LPG) is considered a better fuel than coal for the following reasons.
 a) It has a higher calorific value (50 kJ/g) than coal (30 kJ/g).
 b) It burns with a smokeless flame and hence does not pollute air, whereas coal produces smoke on burning.
 c) It is easier to handle and more convenient to store than coal.
 d) It is a clean domestic fuel and does not produce any harmful gas, whereas coal, on burning, produces carbon dioxide, which causes air pollution.
