What term describes the energy content per unit mass of a fuel, produced by burning fuels?

• A. Calorific value
• B. Specific energy
• C. Thermal value
• D. Heating value

Answer: (C)

Calorific value describes the energy content released per unit mass when a fuel is completely combusted. It tells you how much heat you obtain from a given mass of fuel under specified conditions. Heating value is a common synonym, with higher and lower variants depending on whether the heat of condensation of water is included. Specific energy also means energy per mass, but it’s a general material property not tied specifically to burning, so it isn’t the standard term for energy released by combustion. Thermal value isn’t a standard, precise term in this context and can be ambiguous. So the best description is calorific value (often called heating value).
