Question

1.5g of a fuel on complete combustion in bomb calorimeter raised the temperature of water from 15c to 20.4c the weight of calorimeter with water was 2825g and that of calorimeter alone was 1110g calculate the calorific value of the fuel the water equivalent of the calorimeter was found to be 115g​

Answer 1

Explanation:

Decrease in carbon and hydrogen percentage results in decrease in gross calorific value of coal from 4578 to 2751 kcal/kg, fixed carbon content from 35.6% to 19.9%, with an increase in ash percentage from 29.2% to 46.6%.
