Question

which substance having high calorific value?why?

Answer 1

Hey dear here is your answer


Natural Gas: Highest calorific value. Calorific Value of a fuel is the amount of energy produced by a unit mass of the fuel on its combustion. Natural Gas is at the top of the table at 13Kcal/g followed by Propane and Butane at 11.9 and 11.8 Kcal/g, respectively.


Hope it's help you

Answer 2

HYDROGEN has high calorific value. Its calorific value is 150KJ/g.The reaction between hydrogen and oxygen to produce water is highly exothermic and the heat liberated is 285 kJ/mole. For methane, CH4, the heat of combustion is 890kJ/mole. ... Such a vast difference in the heat of combustion between hydrogen and the other fuels sufficiently explains its very high calorific value.

HOPE THIS HELPS YOU A LOT.......
