Question

L.P.G is liquefied petroleum gas which is a compound of butane and propane and used as:
A. Cooking fuel
B. Motor fuel
C. refrigeration
D. All of these

Answer 1

Hint: The liquefied petroleum gas (L.P.G) has readily burns in contact with air and the energy content is the same as the petrol and heat energy is double of natural gas. Due to its properties L.P.G has various applications.

Complete step by step answer:
The full form of L.P.G is liquefied petroleum gas. It is a non-renewable source of energy like fossil fuel. The liquefied petroleum gas is extracted from natural gases and crude oils. It contains hydrocarbons comprising three or four carbon atoms. Thus, the normal composition of liquefied petroleum gas is propane and butane and minute concentration of other hydrocarbons.
The L.P.G gas is stored in liquid state under high pressure in a tan, cylinder or steel container. The pressure inside the cylinder is dependent on the type of L.P.G present.
As L.P.G burns with a high rate of coming in contact with air and has an energy content same as petrol it shows a wide range of application. It is used in Gas-motor fuel, pyrolysis and cracking, gas processing, domestic consumption like heating and cooking, refrigeration.

Therefore, the correct option is D. .

Note: LPG may leak in the form of gas or liquid. If it leaks it quickly evaporates and forms a heavy cloud of gas which is heavier than air. LPG vapor can move long distances in the ground and basement and on coming in contact with ignition it can explode.
