A gas deviates most from ideal behavior when it is subjected to
  1. low temperature and high pressure
  2. high temperature and low pressure
  3. high temperature and high pressure
  4. low temperature and low pressure

Solution

At high pressure and low temperature, gaseous atoms or molecules get closer to each other and van der Waals' forces operates, so molecules or atoms starts attracting each other. Hence, at high pressure and low temperature gas deviates the most from its ideal behaviour.
