Actually, coal is more dense than water. It has a specific gravity of about 1.3, which makes it 30% heavier for the same volume. When it comes to weight of coal in the tender, its weight would be less than what you'd get just from the density of the coal due to air in the interstitial space between lumps, but the coal can be piled higher than the water, adding to the weight.

This is coal:


This is coal in water:


Any questions?
