Answer 1

1. LPG is considerd as better fuel than coal because LPG is a cleaner fuel, it does not causes pollution on combustion and also it does leaves any residue after burning.

2.LPG is stored under pressure to keep it in liquid form and pressure depends on temperature of atmosphere and gas ,as it released in atmosphere it vaporizes thats why it is stored in steel container.

3.biogas is mixture of hydrogen methane (65-75 percent) hydrogen sulphide and carbon dioxide. it is not a fossil fuel ,materials from plants and animal origin are used to obtain biogas
