Why does gasoline burn?

Gasoline is very important in our life because it is used as a fuel for cars. Gasoline is a liquid fuel. It burns so quickly and with so much heat that it can explode. Gasoline is a mixture of hydrocarbons, substances consisting of carbon and hydrogen. These substances are light liquids boiling at low temperatures. Carbon and oxygen are attracted to each other, like a magnet and iron. When carbon and hydrogen combine, ignition starts. During combustion, a lot of energy is released in the form of heat.

When gasoline burns, hydrogen combines with oxygen to form water vapor. Carbon reacts with oxygen to form carbon dioxide. How does burning gasoline make a car move? Liquid gasoline turns into steam and mixes with air using a carburetor. This mixture enters the cylinder, where it is compressed by a piston moving inside the cylinder.

When the mixture of gasoline and air vapors is compressed, the spark from the spark plug ignites the fuel. A large amount of gas is produced in this small explosion (rapid combustion). The pressure of this gas acts on the piston and moves it inside the cylinder. The piston is connected to a crank that turns easily. The push received from the combustion of gasoline causes the crank arm to turn. This lever, in turn, is connected to the wheels. He sets them in motion.

The gasoline we use is made from crude oil. In the process of distillation, oil decomposes into different parts, one of which is gasoline.

Why is the UK divided into counties?

The modern division of England, Wales, Scotland and Ireland into counties is the result of a long process of historical, legislative, economic and social change over a thousand years. It began in the time of the Anglo-Saxons, when England was divided into regions, the common name of which "shire" (the Russian transcription of the word "shire") is preserved in the names of many modern counties, for example, Yorkshire, Lancashire, etc.

The division into regions stemmed from the principles of local self-government and self-defense. The Norman conquerors who conquered England in 1066 adopted this system from their predecessors.

Subsequently improved, it gradually reached the areas bordering Scotland and Wales. In Wales, the borders of the counties have changed little since the days of the Tudor dynasty, in whose veins English blood mixed with Welsh. Scotland has for centuries had a system of territories ruled by sheriffs, which was very different from the English. The division of Ireland into counties was carried out by the highest feudal nobility in the time of Henry II and further perfected by Oliver Cromwell 5 centuries later.

Over the past centuries, the map of the British counties has undergone constant changes, reflecting changes in the social life of the country. One of the most important factors causing these changes was the movement of population from one region to another, especially from the countryside to the cities during the "industrial revolution".

The largest cities, in which more people lived than in the rest of the territory of a particular county, were withdrawn from the latter in 1929 and turned into separate administrative units. It also happened that one county "swallowed" another! The creation of the Greater London Region in 1965 resulted in the former county of Middlesex being mentioned only on postal envelopes.

In some counties, two capitals appeared, one of which is a historical, and the other is an industrial, commercial and administrative center.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Translucent novelty 18.01.2012

Epson's Moverio video glasses are not the first device of this type on the market, but they have an important feature - translucent displays, thanks to which the user can see everything that is happening around him.

With a diagonal of 0,52 inches, the display resolution is 950x540 pixels. This allows you to create the feeling that you are looking at an 80-inch screen from a distance of five meters. Video can be played in both 2D and 3D. The glasses run Android OS, are equipped with a WiFi adapter, a micro-USB interface and headphones with Dolby Mobile technology support.

The Moverio weighs 240 g without the remote control. In Japan, the device can be purchased for about 60 yen ($000).
