Seema visited a Natural Gas Compressing Unit and found that the gas can be liquefied under specific conditions of temperature and pressure. While sharing her experience with friends she got confused. Help her to identify the correct set of conditions
(a) Low temperature, low pressure
(b) High temperature, low pressure
(c) Low temperature, high pressure
(d) High temperature, high pressure

Correct Answer: (c) low temperature, high pressure 

Explanation: With the help of experiments it can be shown that gases can liquefy at low temperature and high pressures. As these factors affect the interactive force of molecules i.e. the molecules are able to establish a force of attraction between them on lowering the temperature and increasing pressure.
