A gas behaves more closely as an ideal gas at

Explanation

At high pressure : Attraction forces becomes effective between molecules then change in pressure is `(an^(2))/(V^(2))`.
`p_("ideal")=p_("real")+(an^(2))/(V^(2))`
At high pressure : Repulsive forces becomes effective between molecules then change in volume in nb.
`V_("ideal")=(V_("real")-nb)`
At very low temperature : Intermolecular forces become significant. As the molecules travel with low average speed, these can be captured by one another due to attractive forces.
