Question

Under which set of conditions will the ideal gas law give the best approximation for the properties of a real gas?

Answer 1

Low pressure and high temperature will make real gasses behave like ideal gasses.

Answer 2

Answer : A real gas behave ideally at high temperature and low pressure condition.

Explanation :

The conditions for ideal gas are :

Ideal gas are those gas that has no intermolecular attractions.

Ideal gas are those gas that have negligible volume.

The ideal gas equation is,

`PV=nRT`

The conditions for real gas are :

Real gas are those gas that have intermolecular attractions.

Real gas are those gas that have volume.

The real gas equation is,

`(P+(an^2)/(V^2))(V-nb)=nRT`

Thus, A real gas behave ideally at high temperature and low pressure condition.
