Why is LPG considered a good fuel?

Liquefied petroleum gas (LPG) is considered a good fuel because of the following reasons:

1. It has a higher calorific value (50 kJ/g).

2. It burns with a smokeless flame and thus does not pollute the air.

3. It is easy to handle and convenient to store.

4. It does not produce any poisonous gases on burning.
