ideal gases and real gases

Ideal and Real Gases - An ideal gas is one, which obeys the general gas equation of PV = nRT and other gas laws at all temperatures and pressures. A real gas, does not obey the general gas equation and other gas laws at all conditions of temperature..

). This means that 'K' is directly proportional to the number of moles, 'n', i.e., K n or K = nR, where 'R' is the universal gas constant of proportionality. The value of 'R' is same for all gases. However, the numerical value of 'R' varies with the units in which pressure and volume are ..

Atomicity of Gases - Homoatomic molecules have different atomici..

Noble Gases - The amount of all the noble gases put together (Helium, Neon, Argon, Krypton, Xenon and radon) is extremely low in air. These form only 0.94% of the volume of air and as such can be treated as negligible. These gases were found chemically inert (i.e. did ..

The amount of all the noble gases put together (Helium, Neon, Argon, Krypton, Xenon and radon) is extremely low in air. These form only 0.94% of the volume of air and as such can be treated as negligible. These gases were found chemically inert (i.e. did not mix with other eleme..

Expansion of Gases - Gases also expand on heating. Their volume expansion is very much greater than that of liquids. If a gas is heated at constant pressure, its volume increases and if a gas is heated at constant volume, its pressure increases due to expansion. Similarly, if we..

Solubility of Gases - Gases are completely miscible with each other. Gases also dissolve in liquids and solids. Gasses are soluble in liquid to different extents e.g., solubility of hydrochloric acid gas in water is much more than the solubility of oxygen in water. Sol..
