Question

Give reason for the following: 

LPG is a better domestic fuel than wood.

Answer 1

LPG is a better domestic fuel than wood due to: 

1. LPG has higher calorific value, so it produces much more heat on burning than an equal mass of wood. 

2. It burns without leaving behind any smoke. 

3. It burns completely without leaving behind any solid residue but wood leaves behind a lot of ash on burning.
