Volume of a real gas shows deviation from ideal gas on low temperature and high pressure

Only 2 options are correct then

  • Molecules have volume which causes deviations from ideal gases at low temperature.
  • Molecules have volume which causes deviations from ideal gases at high pressure.

There are 2 possible answers here : b and d.

The Ideal Gas Equation is : PV = nRT

Here, when pressure is increased and temperature is lowered, the volume of the molecules will substantially decrease, which means it has deviated from ideal behavior.
