Question 1608. Pick out the wrong statement?

Aromatics have higher specific gravity than paraffins
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
Heavier petrofuels have higher GCV on weight basis (i.e., Kcal/kg) but lower GCV on volume basis (i.e., Kcal/litre)
Higher specific gravity of petrofuels means higher C/H ratio

Discuss Question

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