Question

What are real gases ? And write equation of real gase

Answer 1

Answer:

Real gases are nonideal gases whose molecules occupy space and have interactions; consequently, they do not adhere to the ideal gas law.

One way of writing the equation of state for real gases is PV=RT[1+VB+....], where B is a constant. An approximate expression for B in terms of the Van der Waals' constant 'a' and 'b' is b−RTna.
