Question

A liquid fuel used in homes is:
A. Water
B. LPG
C. CNG
D. Cooking oil

Answer 1

Hint: Depending upon the usage of the mentioned options, we can classify the liquid fuel which is used at home. Fuel can be classified on the basis of their usage in the industries and for household purposes.

Complete step-by-step answer:
Cooking oil or vegetable oil can be used as an alternative fuel in diesel engines and heating oil burners.
When vegetable oil is directly used as a fuel in either modified or unmodified equipment, it is referred to as straight vegetable oil or pure plant oil.
Conventional diesel engines can be modified to help ensure that the viscosity of the vegetable oil is low enough to allow proper atomization of the fuel.
This prevents incomplete combustion which would damage the engine by causing a buildup of carbon.
Straight vegetable oil can also be blended with conventional diesel all produced into biodiesel or bioliquids for use under a wider range of conditions.
Therefore we can say that the liquid fuel used in homes is cooking oil.
So option D is the correct answer.

Additional Information:
Slightly higher acidity is found in virgin olive oil while pure olive oil is a thickest oil of the three and has a strongest flavour and aroma. Undefined pure olive oil is the gold standard for many of the world's best cooks.
Rice bran oil is considered to be having the highest viscosity.

Note: We can also say that cooking oil is plant animal or synthetic fat used in frying baking and other types of cooking. It is also used in food preparation and flavouring not involved in heat such as salad dressing and bread depends like bread dips and may be called edible oil.
