When heat energy flows into a body it warms the body.
If 'm' g of fuel is completely burned and that heat energy is supplied to 'M' g of water to raise its temperature by Deltat^(@)C then arrange the following steps in a sequences to calculate the calorific value of the fuel (a) Determine the heat energy absorbed by water (b) Determine the calorific value by dividing heat energy produced with mass of the fuel (c ) Note down the amss of water specific heat capacity and change in temperature of water (d) Heat energy absorbed by water is equal to heat given by the guel after complete combustion
