Vedclass · Answer

(A) The polluting strength of hydrocarbon fuels depends on the completeness of combustion and the presence of impurities.$1$. $CNG$ (Compressed Natural Gas) is the cleanest fuel among these as it burns completely with minimal pollutants.$2$. $LPG$ (Liquefied Petroleum Gas) is cleaner than liquid fuels like kerosene but produces more pollutants than $CNG$.$3$. Kerosene is a liquid hydrocarbon fuel that produces more smoke and pollutants compared to gaseous fuels like $LPG$ and $CNG$.Therefore,the increasing order of polluting strength is: $CNG < LPG < 	ext{Kerosene}$.

List-$I$	List-$II$
$A$. Toxic heavy metals	$1$. Soil erosion from agricultural and mineral industries.
$B$. Pesticides	$2$. Domestic sewage disposal.
$C$. Sediments	$3$. Chemical factories and industries.
$D$. Microorganisms	$4$. Substances used to kill insects,fungi,and weeds.

Arrange the following hydrocarbon fuels in increasing order of their polluting strength: $LPG$,$CNG$,and Kerosene.
