Chemistry is the state in which atoms or molecules are in nature. The material has three conditions: solid or rigid, liquid, and invasive. Gases are a form of matter that is fluid like liquids. It is called a liquid because it has the characteristic of moving from place to place, in addition to filling the container in which it is placed, whatever its size. Gases are found in nature in the form of binary molecules consisting of either atoms of the same kind as noble gases - elements of the eighth group of the periodic table - argon and neon, or other gases such as oxygen, nitrogen, iodine and others, or atoms of more than one type, - nitrogen monoxide - a component of oxygen and nitrogen - and methane - a component of hydrogen, carbon - and other gases.
Gases are made up of particles that are spaced in their structural structure, allowing them to move quickly across the entire size, causing collisions between them, resulting in an exchange of energy.
This explains the rapid spread of fragrance in the room as soon as the fragrance is sprayed in any corner Of which.
The relationship between the large distance between the particles of gases and the temperature is a direct relationship; the greater the temperature affecting the gas increased the distances between the molecules and thus reduce the density of gas and vice versa.
Gases in general are compressible in packages or cylinders, such as domestic gas cylinders and others. Gases have the ability to liquefy, that is to be converted into liquid, a liquefied gas.
The size of the gas varies according to the container in which it is placed; the amount of gas that fills the size of the room, for example, is the same as that which can be filled in a cylinder or a bottle; the gas takes up the size of the space in which it is located.
Temperature: Gas is affected by high and low temperature; heat affects the bonds between its molecules, increasing its movement by increasing or decreasing its movement.
Pressure: Gas pressure is affected by the pressure; the more pressure on the molecules of gas increased the convergence between them and thus reduce the size, and the less pressure the increased volume of gas.
It can be compressed gases measured using Almanomitr device, which is a U-shaped in English, so that one end of the U-shaped open and the other end connected to the vasa containing the gas to be measured pressure, and is used Almanomitr to measure gas pressure which does not exceed the amount of atmospheric pressure.
