Question

Petroleum is a dark oily liquid with unpleasant smell that does not burn, but

still called a fuel, because

(A) it is made from dead remains of marine plants.

(B) it is insoluble in water and floats on it.

(C) it is refined to get different constituents with excellent calorific values.

(D) of its colour and appearance.​

Answer 1

1. Petroleum (also known as crude oil or simply oil) is a fossil fuel that was formed from the remains of ancient marine organisms. Millions of years ago, algae and plants lived in shallow seas.
2. Oil does not dissolve in water so it is insoluble in water but floats on the surface of water. 3.Natural gas is mainly Methane and has the lowest carbon-to-hydrogen ratio of the fossil fuels and the highest calorific value of about 55 MJ/kg, although this value will be lower if the methane content in the gas is lower. What Is Appearance? Color is only one aspect of an object's appearance. In fact, the way you perceive an object's color may change depending on other aspects of appearance, including characteristics such as texture, gloss and transparency. A smooth or high-gloss surface facilitates specular reflection.
