2. On burning 0.83 g of a solid fuel in a bomb calorimeter,
the temperature of 3,500 g of water increased from
26.5°C to 29.2°C. In another experiment in the same
calorimeter 0.5 g of naphthalene (HCV = 9,688 kcal/kg)
was burnt and temperature was increased form 25.5°C
to 29.2°C. Latent heat of evaporation of water is 587.0
cal/g and the fuel contains 0.7% hydrogen, calculate its
gross and net calorific value.​
