A stove is one of the most common heating devices used in everyday life. Stoves burn the fuel in them and generate heat. Stoves use different fuels for heating. Not all the heat energy produced by the burning fuel reaches the object being heated. Total heat produced due to burning of fuel (formula_1) is not equal to the amount of heat absorbed by the object (formula_2). So some mass of water should be taken in a beaker. Determine the initial temperature of the water. Find the mass of the heating device (lamp). Heat the water in the beaker for 5 minutes. Calculate the final temperature of the water. Switch off the heater. Now calculate the mass of heater. Now calculate the mass of fuel used by the heating device. This value is generated by the heating device multiplied by the calorific value of the fuel in the heating device
