Question

Domestic cooking gas cylinder is filled with
A. Alcohol
B. Diesel oil
C. Liquid petroleum Gas
D. Coal gas

Answer 1

Domestic cooking gas uses a combustible material which is hydrocarbon-based. The gas used for combustion is mostly colourless and odourless. It is produced by the process of refining crude oil.

Complete step by step answer: Gases filled in domestic gas cylinders are propane and butane. It is generally filled in cooking appliances, vehicles and some other heating devices. It is derived from the fossil fuel reservoirs and are manufactured during the refining process of crude oil. Gas is then delivered to consumers by filling into cylinders. LPG is preferred over other fuels because it can be easily liquified under pressure, easy storage, and a simpler method of transportation through steel cylinders. It vaporizes easily even at low temperatures. LPG is a nontoxic gas and does not possess any deleterious effects on the human body on inhalation. The other given options such as alcohol, diesel oil and coal gas are not used in the domestic cooking gas cylinder. Coal gas is not extensively used in cooking since it being a fossil fuel and its rate of formation is very slow and the over usage of it results in the rapid depletion of the levels, and there is a need for its conservation.
Thus the most appropriate option is C that is, liquefied petroleum gas is the filling material in a domestic cooking gas cylinder.
Hence, the correct answer is option C.

Note: Gases included in LPG are colourless and odourless, and odour has been externally included to detect any kind of leakage from the cylinder and avoid accidents. The chemical thus added is methyl mercaptan, it is also known as the stench gas, due to its unpleasant characteristic smell.
