Question

In an experiment,50 kg of a fuel wadms completely burnt. The heat produced was measured to be 150,000 J. The calorific value of the fuel is

Answer 1

Here we will use the following procedure;

To determine the calorific value =150000 J / 50kg

Calorific value= 3,000 J/kg

Calorific value is normally measured using a type of calorimeter known as the bomb calorimeter.

This is arrived at when a of a known mass of fuel in the calorimeter is ignited which then is used to heat water and the initial and final temperature are recorded.
