Answer 1

${\fbox{\purple{Question-}}}}$

In an experiment 4.5 kg of a fuel was completely burnt.The heat produced was measured to be 180000 kJ calculate the calorific value of the fuel​?

$\pink{\bold{\underline{\underline{SolutiOn-}}}}$

The calorific value of fuel is the amount of heat produced by the complete combustion of 1 kg of fuel.

Heat produced by 4.5 kg of fuel = 180000 kJ.

Heat produced by 1 kg fuel =   

                                             ​= 40000 kJ.

Hence, the calorific value of the fuel is 40,000 kJ.
