Why does a real gas obey Boyle's law and Charle's law at low pressure.

Explanation

Low pressure: In this case the distance between and molecules is so high that the force of attraction among them is very small,so the molecular potential energy may be neglected.
In these two cases, a real gas molecule essentially has a kinetic energy only. So it behaves as an ideal gas and obeys Boyle.s and Charle.s law.
