  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 remember the correct set of conditions. 

Answer:

                  On applying low temperature, the kinetic energy of the particles decreases and the particles come closer. Increased pressure also brings the particles closer, so the gases liquefy. Hence, the conditions are low temperature and high pressure.
