Question

which forces is used to show the deviation between realgases and ideal gases​

Answer 1

Answer:

In 1873 Van der Waal determined that real gases show deviation from ideal behaviour at temperature and high pressure. It is due to two false points Kinetic molecular theory of gases which are given as: I. The molecules of a gas have no force of attraction.

Explanation:

The contribution of intermolecular forces creates deviations from ideal behavior at high pressures and low temperatures, and when the gas particles' weight becomes significant.
