What is the difference between petroleum and gasoline?

Gasoline is extracted from petroleum and is a transparent liquid, mainly used as automobile fuel. It is a transparent, liquid, volatile, flammable hydrocarbon mixture liquid. The following is a detailed introduction to the difference between petroleum and gasoline. I hope we can have more relevant knowledge about fuel and energy!

What is the difference between oil and gasoline?

The difference between oil and gasoline lies in their source, color, and use. Oil is a black, flammable, viscous liquid extracted from deep underground. It is mainly used to refine fuel oil or make plastics, fertilizers and other substances. Gasoline is refined from oil and is a transparent liquid. It is mainly used as automobile fuel.

1. Different sources

Oil and gasoline have different sources. Oil is a substance extracted from deep underground. It is a mixture of substances formed by organisms in ancient oceans or lakes after a long period of evolution, while gasoline is a product refined from oil as raw material.

2. Different colors

Oil and gasoline have different colors. Oil extracted from deep underground is black in color, viscous in texture, and liquid, while gasoline refined from oil is transparent and liquid.

3. Different uses

Oil and gasoline have different uses. Depending on the length of the hydrocarbon molecular chain, gasoline, diesel and other fuel oils can be extracted from oil. Oil can also be used as a raw material for fertilizers, pesticides, and plastics, but gasoline is often used as a fuel for tools such as cars and fuel engines.

Gasoline specific gravity

The specific gravity of gasoline is about 0.7g/ml to 0.78g/ml. Different types of gasoline have different specific gravity. Under standard conditions, the specific gravity of No. 90 gasoline is 0.72g/ml, the specific gravity of No. 93 gasoline is 0.725g/ml, and the specific gravity of No. 97 gasoline is 0.737g/ml.

According to the principle that mass equals volume times density, we can calculate that 1 liter of No. 90 gasoline is equal to 0.72 kilograms, 1 liter of No. 93 gasoline is equal to 0.725 kilograms, and 1 liter of No. 97 gasoline is equal to 0.737 kilograms.

Specific gravity, also known as relative density, is the ratio of the density of a solid or liquid at standard atmospheric pressure to the density of pure water at 3.98°C. The specific gravity of a gas refers to the ratio of the density of the gas to the density of air under standard conditions.

In some books, people also translate the weight of a substance contained in a unit volume into specific gravity, which can generally be used to refer to the sinking or floating of an object in water. It is commonly called unit volume weight and can be represented by the symbol ω.

Does a liter of water weigh the same as a liter of gasoline?

One liter of water and one liter of gasoline are not the same weight. The density of one liter of water and one liter of gasoline is different. According to the formula, mass equals density multiplied by volume. Under the same volume, the greater the density, the greater the mass. The density of the same volume of water is greater than that of gasoline, so one liter of water is heavier than one liter of gasoline.

Under standard conditions, the density of water is equal to 1g/ml, the density of gasoline is approximately between 0.7g/ml and 0.78g/ml, the mass of one liter of water is one kilogram, and the mass of one liter of gasoline is between 0.7 kilograms and 0.78 kilograms.

If you don't know the density, you can mix water and gasoline. If the gasoline floats on the water, it means that the density of gasoline is smaller than that of water, so the weight is smaller for the same volume.

Gasoline is a volatile and flammable hydrocarbon mixture liquid obtained by distillation and cracking of petroleum. It can be divided into types such as No. 89, No. 90, No. 92, No. 93, and No. 95 according to its octane number.
