Answer 2

Q-The main constituent of LPG is-

b) butane , and (d) propane

Both are present in good amount.

But if one answer is required so it is,

b) butane

The main constituents of LPG are butane and propane. Both of them are mixed to form LPG.

The percentage of both butane and propane gases in the mixture of LPG tends to vary from 100% of propane to 20% of propane and about 80% of butane.

LPG stands for liquefied petroleum gas. Like all fossil fuels, it is a non-renewable source of energy. It is extracted from crude oil and natural gas. LPG is composed hydrocarbons containing three or four carbon atoms. The normal components of LPG thus, are propane (C3H8) and butane (C4H10). Small concentrations of other hydrocarbons may also be present.

LPG burns readily in air and has an energy content similar to petrol and twice the heat energy of natural gas. This makes it an excellent fuel for heating, cooking and for automotive use.

Normally, the gas is stored in liquid form under pressure in a steel container, cylinder or tank. The pressure inside the container will depend on the type of LPG (commercial butane or commercial propane) and the outside temperature.
