A gas with: low pressure, low concentration, low temperature.
low pressure and high temperature
This is a gas having a high concentration.
Real gases approach ideal behavior at high temperature and low pressure. In this Condition gases occupy a large volume and molecules are far apart so volume of gas molecules are negligible and intermolecular force of attraction(responsible for non ideal behavior) become low. So gases approach ideal behavior.
When the pressure is low and the temperature is high the molecules have less inter particle forces of attraction thus more inter particle spaces, which is a characteristic of gases .Therefore it is an ideal situation for gases.
low pressure and high temperature
A gas with: low pressure, low concentration, low temperature.
High pressure, and low temperature.High pressure, and low temperature.High pressure, and low temperature.High pressure, and low temperature.
Gases show least ideal behaviour at 1- high pressure and 2- low temperature.
Helium
That's called an "ideal gas". The behavior of real gases is quite similar to an ideal gas, except when the pressure is too high, or the temperature too low.That's called an "ideal gas".

High temperature; low pressure.

During low pressure, and low temperature conditions
This is a gas having a high concentration.

So gases approach ideal behavior.
An ideal gas is, precisely, an idealization - a ficticious substance that will NOT liquify, but remain a gas, and have a volume that is exactly proportional to the temperature (at a given pressure). Real gases are an approximation to an ideal gas, under a wide variety of conditions, but at low temperatures, or high pressures, there are discrepancies.
