Answer 1

Answer:

Calorific value: The amount of heat energy released on complete combustion of 1 kg of a fuel is called calorific value. It is expressed in a unit called kilo joule per kg (kJ/kg). Calorific value = heat produced / weight of fuel used in Kgs Heat produced = 180000 kJ Weight of the fuel used in Kgs = 4.5 Calorific value = 180000/ 4.5 = 40000 kJ/kg
