Combustion and Flame
The calorific value of a fuel is expressed in a unit called as ______________.
What do you understand by fuel efficiency?
Fuel efficiency is the amount of energy produced on burning 1 kg of complete fuel. This is determined by caloric value. This is expressed in kJ/kg
The calorific value of a fuel is expressed in a unit called as ______________.
Some words (underlined) in the following sentence are jumbled up. Write them in their correct form. The amount of heat energy produced on complete combustion of 1 kg of a fuel is called its ficalroic value.
Indicate whether the following statement is True or False. Also, write the false statements in their correct form. The calorific value of wood is higher than that of coal.
Fill in the blanks: The amount of heat energy produced on complete combustion of 1 kg of a fuel is called its ____________.
Write True/False against the following statements and also correct the false statement. Greater the calorific value better is the fuel.
The calorific values of petrol and CNG are 45,000 kJ/kg and 50,000 kJ/kg, respectively. If you have a vehicle which can run on petrol as well as CNG, which fuel will you prefer and why?
Although wood has a very high calorific value, we still discourage its use as a fuel. Explain.
