A. Aromatics have higher specific gravity than paraffins

B. Gross calorific value (GCV) of petrofuels is equal to (12400 - 2100 ρ²) where, ρ is the specific gravity of the fuel at 15.5°C

C. Heavier petrofuels have higher GCV on weight basis (i.e., Kcal/kg) but lower GCV on volume basis (i.e., Kcal/litre)

D. Higher specific gravity of petrofuels means higher C/H ratio
