Chemistry: Objects indicate molecules and, as a certain set of them through physical properties, such as their volume and collective form, their reaction to temperature and Their reactions to the pressure of matter, the properties of the properties of the nature of the atoms and the specific molecules are shown because the solid consists of solid objects that can be crystals, which is available. This means that they have a very orderly structure for the Kules of the group to create solids, or solids that can be amorphous and not symmetrical in handling particles, solid forms in a liquid state. The material flows to obtain the shape of each container, but the liquid is limited against the change due to the pressure that the gas condition also means the shape of a container is different from the liquid because it extends to the quality. The most important container that increases the size of the container, expanded gas to fill the temperature, pressure and number of molecules to determine the volume of a volume of gas can always be mixed, more Used in certain contexts more in the condition to describe the physical properties of different phases and separate from the state, a different phase in which individual units such as the mixture in the plasma of their of The state of liquid is called the state of the physical state. It is not often on the surface of the earth, but 90% of the room materials are in the state of the plasma, the natural plasma forms an electrolyte layer, a layer of polluted particles with low density in the upper atmosphere soil. Plasma status is similar to the gas state, except it does not contain the atoms and molecules of the atomic particles such as electrons that are negatively emphasized and positive ions of the Latin words for the terms that the terms that the term gas has a story. During the Renaissance (1400-1650), it could be followed by Baptiste Van Helmont (1579-1644) after January. Becoming a part of the development of modern chemistry. He According to the famous scientist of Van Helmont, Robert Boyle (1627-1691), experienced his tune observations in a contract and announced his melody observations in 1660. GAS. He is the second scientist of the scary law, Joseph Louis Gay -Losac (1778-1850), called the "Law" Charles, has experience in private gas reactions and discovered that they are still in newspapers. The fox about the mass of a small number published their conclusions in 1808. Physicist Amadeo Avagadro (1776-1856) proposed in 1811 that the gas volume was determined by the number of gas molecules existed. Available in Avogadro hypotheses. There is no atom to determine the volume of gas at a certain temperature and the presentation of atoms includes the type of oxygen of the corresponding molecule, there are two atoms in a steam molecule with three and methane, often searching Seeing in the decomposition materials there are four combinations of all individual contributions. The number of molecules with constant multiplier with molecules is compensated by gas to connect different units used in measurements. Physicists have conducted physical material studies, especially at the level of nuclear and molecules, the condensing physics are also known as solid physics in solid, solid physics under the part of the object. Whether soft condensation is recorded in collections of indigenous crystals in prehistoric times with vulnerabilities and engraved with ancient Greeks. Haüy (1743 balls1822) When he launched a good glass of Calcite of a French cashier collection to check the pieces, Haüy noticed regular and repetitive forms, among all the Part 1817 is the story of this discovery and later his work on crystals in a certain shadow of books including the work of a crystal (treated on the crystal). Haüy's work is considered the beginning of the important crystal science, which has led to a great progress in the understanding of the chemical structure of SOLIDWHEN x Crylalline Strays, research on German physicist Max Von Von Von Von Von Von Von Von Von Von Von Von Von Von Von Von Von Von Von Von Laure (1879-1960) Nobel Awards in 1914 and the team of British physicists Sir William Henry Bragg (1862-1942) and William Lawrence Bragg (1890-1971) Nobel Award in 1915 for their contributions at them in At the time of Xlograph, it provided the first studies to provide research from glass molecules that information about many connections including protein and polymers, without "Eureka!" However, the time related to the history of the liquid state of matter is significant and significant chemistry. And John Dalton has promoted the theory of atoms and molecules, British botanists Robert Brown (1773-1858), observing the random and non-stop movements of floating pollen particles in the country This observation in 1827 was known as a brown motion that I did not try to explain the movement, but in 1905, German-American physicist Albert Einstein (1879-1955) said that the movement was the movement was The result of a random heat motion of liquid liquid The gas is summarized as random molecules with completely elastic collisions of existing collisions because they broke the walls of their limitations in liquids. It depends on the type of molecule and the way they interact, and the temperature of the solid has a random thermostat, depends on the type of molecule and the temperature of the vibrating solid molecules, they do not move one. The room is like liquid molecules; For this reason, a solid implies a fixed state that implies additional (or except) heat to change the level of movement of molecules, meaning that the temperature of solid is pure, Encore , Bis is to change the heat that increases molecular vibration to melting temperatures because it is not hotter, but the heat causes the relationship between molecules if enough heat has been added to break and break socks Both molecular links, solid soil and soil and it become a liquid. The essential heat to melt a pure solid is called a synthetic reaction heat for this indications in motion and the increase in temperature is heated liquid until the feces. The liquid death reaches the temperature, the molecules increase their speed until the point. The molecules if the low bond can escape, still close to the steam point, the temperature does not return to the liquid is completely converted into gas as soon as it goes into the gas and adding heat increases the temperature and the temperature but the temperature It increases again to convert a refined liquid when the gases lead to air contracts from the air in 1660 are active and negative with modern theories of chemical and atomic elements. And the molecule, scientist Joseph Priestley (1733-1804) on intensive logistics, in theory of this moment that a mysterious substance is called Flogiston Est Aba in all substances. The confusion about what Priestley has discovered a factor that according to his definition, is a unique chemist that Priestley did not accept to Lavoissier that the current concept of very limited factors, but but Lavoisers have won among scientists and discovered more factors more accelerating, the people whose parts also appear in the appearance of theory including atoms and molecules, although theory This was not accepted at that time, when Dalton and Avogadro promoted their ideas, won the increasing popularity of the quietest Lavoissier ideas, his career was a modern chemistry, Suddenly, the end of Lavoissier was not only a chemist, but also the aristocratic situation of his family, who caused his death in the guillotine in the French Revolution (1789-1799), a one The article in the additional development of the concept that the material made from atoms is done in the view of the movement of the movements. Liquid molecules caused movement from Brown when Einstein a theoretical physics is his idea in 1905, it is not a good organization science. Due to the contribution of Einstein and the advancement of physics, leading to the development of atomic energy, solid state is a physical state in physical state based on substances and crystals. In cholesterol, they do not melt at the same time, because a pure solid must have the consolidation of the substance at 229 ° F (145 ° C), the crystals melted with an uneasy liquid with the heating system Sung in 288 ° F (178 ° C) it has been proven in a connection with clear liquid, in which German physicist Otto Lehmann (1855-1922), an optical glass expert. If he can help explain the abnormal union of crystals based on Lehmann's cholesterol. Regarding the problem he described as a researcher as a liquid crystal. In the process of detecting liquid cholesterol crystals, it has been proved that other substances, usually sticky molecules, have also formed liquid crystals. The new issue was tested in the 1960s by French physicist Pierre-Gilles de Gennes (1932-2007) that in 1991 received the Nobel Award for his contributions to the liquid crystal science. . Liquid crystals are used in electronic devices. Information is displayed for everything, mobile phones with flat screen for computers and TVs. Liquid crystals are possible by genes for liquid crystals. For electrodes attached to plasma cells, the advantage of the wider angle view than the more liquid crystal screen. Asthma is also used in fluorescent light and neon signs, which scientists working in plasma reactors can only create a large day using the same merger, also Used in solar radiation.
