Explanation:

low pressure and low temp

For ideal gas behavior, the inter-molecular force among gas molecule should be negligible, and and size of molecules should be very less compared to the free space.

A gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to inter-molecular forces becomes less significant compared with the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.

So, at high temperature and low pressure, behavior of gases can be approximated by that of an ideal gas and they follow ideal gas equation, PV=nRT
