Explain about Real gas in brief.
Answers
Explanation:
What is real gas?
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.
Related Information:-
➲ Real gases have a very low pressure.
➲ These gases have high temperature.
➲ On considering the compressibility factor(z), the compressibility factor (z) is, Z = PV/nRT
➲ So For real gas, z ≠ 1
➲ It means, PV ≠ nRT.
Extra Information:-
➲ The van der Walls equation is that equation which is valid for real gases.
➲ The two properties of real gases are the
- excluded volume of gas particles represented as 'b' and
- attractive forces between gas molecules as 'a'.
➲ The formula for Van der waals Force is:
[P + a(n/V) ²][V-nb] = nRT
Explanation:
Real gases are nonideal gases whose molecules occupy space and have interactions; consequently, they do not adhere to the ideal gas law. To understand the behaviour of real gases .
