Gas Laws

Gas method Since the Aristotle era, all substances were divided into one of three material states. A substance having a fixed volume and shape is a solid. A substance that has a constant volume but does not have a constant shape is a liquid and the liquid takes the form of its container but does not need to be filled. A substance that does not have a constant shape or constant volume is a gas, which gas indicates the shape and volume of the container. The structure of the gas and its behavior is simpler than the two condensed phases, the structure and behavior of solids and liquid Pressure and Boyle 's law quantitatively measures the gas first in a reasonable way.

Boyle's law (also called Boyle-Mariotte's law) is one of the laws of gas, which is the derivation criterion of the ideal gas law and represents the relationship between product pressure and volume in a closed system with constant temperature I will. Constants are fixed. The law was named for chemists and physicists Robert Boyle, Robert Boyle published the original law in 1662. French physicist Ed Maryriot discovered the same law in 1676 irrespective of Boyle. Black hole theory: in the article of "philosophical trading" in 1783 John Michelle. The Royal Society said, "If the radius of the sun is the same as the density of the sun, it is 500 to 1, light is drawn by the same force in proportion to other objects, all light emitted from such objects Pierre - Simon Laplace proprietarily proposed a similar idea after a few years.

An ideal gas is a gas physically fitting a specific ideal relationship between pressure, volume, and temperature. The ideal gas law is a generalization including Boyle's law and Charles's law as a special case, and for a given amount of gas, the product of volume V and pressure P is proportional to absolute temperature T indicate. Where k is a constant. The relationship of this substance is called its state equation and is sufficient to explain its overall behavior.

Ideal gas method is the most useful method and should be remembered. If you understand the ideal gas method, it is a combination of all other laws, so you do not need to know other gas laws. If you know three of the four state variables of gas, you can find something unknown by this rule. If there are two gases with different state variables, you can compare them. This form can be used to predict the effect of changing state variables. In order to keep the value of R constant, as the numerator changes, the denominator ratio must also change, and vice versa. For example, if the pressure drops in a constant volume vessel, you can easily predict that this table should be used to lower the temperature.
