Expert Answer
Calorific value of Alcohol (Ethanol) = 29,700 kJ/kg
Calorific value of CNG (Compressed Natural gas) = 50000 kJ/kg
Calorific value of Cooking gas (LPG- Liquified Petroleum Gas) = 55000 kJ/kg

Thus,
In ascending order,
Alcohol> Natural gas> Cooking gas  ... (according to their calorific values)
