In an experiment 4.5 kg of a fuel was completely burnt. The heat produced was measured to be 180,000 kJ. Calculate the calorific value of the fuel. |
| Answer» TOTAL mass of fuel = 4.5 kg Total HEAT produced = 180,000 kJ Heat produced by BURNING 1 kg of fuel = 180,000 kJ/4.5 kg = 40,000 kJ/kg. So, calorific VALUE of fuel = 40,000 kJ/kg.mark as brainlist | |
