for fuels it should be high

Answer 2

Calorific Value

Explanation:

The calorific value of a fuel is the quantity of heat produced by its combustion – at constant pressure and under “normal”  (standard) conditions. The calorific value of a fuel is expressed in a unit called kilojoule per kg (kJ/kg). Diesel has the highest calorific value among the listed fuels. The calorific value of diesel fuel is roughly 45.5 MJ/kg (megajoules per kilogram), slightly lower than petrol which is 45.8 MJ/kg. However, diesel fuel is denser than petrol and contains about 15% more energy by volume.
