Question

Good fuel is one which has a

• A. low calorific value
• B. high calorific value
• C. medium calorific value
• D. no calorific value

Answer 1

The correct option is B

high calorific value

The quality of fuel depends on its calorific value. Calorific value is the amount of heat generated when unit mass or unit volume of fuel is burnt in a sufficient supply of oxygen, i.e., burning 1 kg of coal generates more heat than burning 1 kg of wood because the calorific value of coal is greater than the calorific value of wood.
