Question

When does real gases obey ideal gas equation?

Answer 1

at high temperature and low pressure hope this helps you

Answer 2

Answer:

An ideal gas is one whose molecules have zero volume and no mutual force between them. At low pressure, the volume of gas is larger than show the volume occupied by the molecules is negligible in comparison to the volume of the gas point at high temperature, the molecules have larger velocities and so the intermolecular force has no influence on their motion. And at low pressure and high temperature the behaviour of real gas approaches to the behaviour of ideal gas.
