Options
low temperature, low pressure
high temperature, low pressure
low temperature, high pressure
high temperature, high pressure
Solution
low temperature, high pressure
With the help of experiments it can be shown that at low temperature and high pressures, gases will liquefy. Because these factors affect the interaction force of molecules i.e. the molecules are able to establish a force of attraction between them on lowering the temperature and increasing pressure.
