Question

Write something about Real gas in brief.​

Answer 1

A gas which doesn't follow ideal gas behaviour that is obeying all gas laws at any temperature and pressure is called as real gas.

Special Points:-

1. Real gases have a very low pressure.
2. These gases have high temperature.
3. On considering the compressibility factor(z),
4. The compressibility factor (z) is ;
5. Z = PV/nRT
6. So For real gas, z≠1
7. So, PV≠nRT.

Answer 2

Answer:

Explanation:

Gases that deviate from ideality are known as Real Gases, which originate from two factors: (1) First, the theory assumes that as pressure increases, the volume of a gas becomes very small and approaches zero. While it does approach a small number, it will not be zero because molecules do occupy space (i.e. have volume) and cannot be compressed. (2) Intermolecular forces do exist in gases. These become increasingly important in low temperatures, when translational (definition of translational, please) molecular motion slows down, almost to a halt. However, at high temperatures, or even normal, every day temperatures, the intermolecular forces are very small and tend to be considered negligible.
