Question

in an experiment 5 kg of a fuel was completely burnt calculate the calorific value of the fuel is the heat produced was measured to be 200000 kj

Answer 1

In an experiment 5 kg of a fuel was completely burnt, the calorific value of the fuel for the heat produced measured to be 200,000 kJ is 40,000 kJ/kg.

• Total mass of fuel in the experiment = 5 kg
• Total heat produced in the experiment = 200,000 kJ
• Heat produced by burning 1 kg of fuel can be expressed as,

                                    200,000 kJ/5 kg = 40,000 kJ/kg.

So, calorific value of fuel is given by 40,000 kJ/kg.

Answer 2

Answer:

formula = kj/kg

= so, 200000/5

=200000/5

ans) 40000
