Which fuel has the highest density ?
Coal
Density is mass per unit volume; for solid fuels a higher density means more fuel (and generally more energy) packed into a given volume, which matters for transport and storage.
Coal is a compact fossil fuel formed by the compression of plant matter over millions of years; its density is about 1.1–1.5 g/cm3 (roughly 700–900 kg/m3 as loose bulk).
Biomass fuels are much lighter: fuelwood has a density of about 0.4–0.8 g/cm3, dried dung cakes are porous and light, and loose crop residues such as straw and husk have very low bulk densities (often below 0.15 g/cm3), which is why they are briquetted.
Hence, the answer is Coal.
