Question

17. in an experiment 3.5 kg of a fuel was completely burnt. the heat produced was found to be 210,000 kj. calculate the calorific value of the fuel.​

Answer 1

Explanation:

Mass M = 3.5 kg

Heat H = 210000 kJ

Calorific value means amount of heat produced on burning 1 kg of substance.

$calorific \: value \: = \frac{heat}{mass}$

$calorific \: value \: = \frac{210000}{3.5}$

= 60000 kJ/kg
