What are the advantages of using CNG and LPG as fuels?
CNG is comparatively light weight because of greater no. of hydrogen atoms and as being gas, it is safer and can leave to atmosphere easily so it could be a good source of fuel in car, motors and industries etc. which cause huge pollution so that by using CNG the pollution level is decreased and safety is increased.
While, LPG is heavier than air and and so does not releases after leakage and so very unsafe in industries but it is useful in cooking as the cooking needs a continuous supply of fuel which maintains flame of the gas stove and so the LPG as being liquefied, fulfill all the requirements of a cooking fuel.
