Question

This equation is used to calculate the properties of a gas under nonideal conditions.

Answer 1

Answer:

Van der Waal's equation

Explanation:

The Van der Waal's equation is use to calculate the properties of a gas under nonideal or real gases conditions.

$(P + \frac{an^2}{V^2})(V-nb) = nRT$ .

Here P, V ,T ,n and R have usual meaning as in the ideal gas equation

that is PV=nRT

with the difference of constant a and b.  a and b are constants representing magnitude of intermolecular attraction  and excluded volume respectively respectively.
