उत्तर

  1. Carbon and its compounds are used as fuels because of their high hydrogen and carbon content; they release a significant amount of heat during combustion.
  2. Fuel-grade carbon compounds are straightforward to work with and have high calorific values and ideal ignition temperatures.
  3. There is control over their combustion. Carbon and its components are therefore employed as fuels.
