1. Coal is an allotrope of Carbon
2. Petroleum is a mixture of hydrocarbons (containing both carbon and hydrogen)
3. Ammonical liquor is obtained in the destructive distillation process of coal.
Thermal power plants generally use steam coal which is a grade inbetween bituminous and anthracite.
LPG is filled under pressure so that it is liquified and in that state it occupies more volume than that in gaseous state. Also liquids catch fire slowly.
Biogas is gaseous fuel especially methane produced by fermentation of organic matter.
