Ideal and Real Gases
Ideal gases obey conditions of the general gas laws under all states of pressure and temperature. Ideal gases are also named perfect gases. The attributes of ideal gases are as follows,
Gas Laws
Gas laws describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. The very first observations about the physical properties of gases was made by Robert Boyle in 1662. Later discoveries were made by Charles, Gay-Lussac, Avogadro, and others. Eventually, these observations were combined to produce the ideal gas law.
Gaseous State
It is well known that matter exists in different forms in our surroundings. There are five known states of matter, such as solids, gases, liquids, plasma and Bose-Einstein condensate. The last two are known newly in the recent days. Thus, the detailed forms of matter studied are solids, gases and liquids. The best example of a substance that is present in different states is water. It is solid ice, gaseous vapor or steam and liquid water depending on the temperature and pressure conditions. This is due to the difference in the intermolecular forces and distances. The occurrence of three different phases is due to the difference in the two major forces, the force which tends to tightly hold molecules i.e., forces of attraction and the disruptive forces obtained from the thermal energy of molecules.

Converting between Units of Pressure
Gases are different from solids and liquids. In a sample of
gas, the molecules are far apart. The gas molecules also
move around and collide with each other as well as with the
walls of the container. These collisions generate pressure
The pressure of a gas can be measured in different units.
One convenient unit of measure is called the atmosphere (
atm) because it is based on atmospheric pressure. At sea
level, the average pressure is 1 atm. As you get higher in
altitude, the pressure steadily drops until you leave the
atmosphere, where the pressure is very close to 0 atm
The table below shows the different commonly used units of
measuring gas pressure. Use this table in the pressure unit

High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purify chemical substances. The pressures used
in this procedure range from around 500 kilopascals (500,000 Pa) to about 60,000 kPa (60,000,000 Pa). It is often convenient to know the
pressure in torr. If an HPLC procedure is running at a pressure of 4.02-108 Pa, what is its running pressure in torr?
Express the pressure numerically in torr.
