22) Under which conditions does a real gas behave most nearly like an ideal gas?

1. low pressure and high temperature
2. low pressure and low temperature
3. high pressure and high temperature
4. high-pressure and low temperature
5. None of the above

A real gas will behave more like an ideal gas when there is low pressure, so that fewer particles occupy the volume of a container, and high temperature, so that the attractive forces between particles have less effect because the particles move with high-speed.
