Combustion and Flame
The calorific value of a fuel is expressed in a unit called as ______________.
Write True/False against the following statements and also correct the false statement. Greater the calorific value better is the fuel.
Calorific value means the energy contained in fuel or food, determined by measuring the heat produced by the complete combustion of a specific quantity, expressed as $$J/kg$$.
The greater the calorific value, the better is the fuel.
So, the given statement is true.
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 ____________.
What do you understand by fuel efficiency?
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.
