Coal Density - an overview | ScienceDirect Topics
Coal density is among the important parameters for reservoir engineering purposes and is inserted as an input property in simulation studies. Coal density is typically less than that of conventional reservoirs and differs from seam to seam based on the given coal rank and purity [2].The bulk density of a coal consists of the matrix and the void space, with the latter being expectedly filled ...

The Density of Common Rocks and Minerals
The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).

Energy density - Energy Education
Energy density is the amount of energy that can be stored in a given system, substance, or region of space. Energy density can be measured in energy per volume or per mass. The higher the energy density of a system or material, the greater the amount of energy it has stored. A material can release energy in four types of reactions.

Relative coal density is measured as specific gravity. Specific gravity is the ratio of the mass of an object (solid or liquid) to the mass of an equal volume of water at 4°C. For reference, the specific gravity of water is 1. Materials with specific gravities of less than 1 float in water. Specific gravities that are greater than 1 sink in water.

Energy Density of Coal ~ Coal Energy
The energy density of coal, i.e. its heating value, is roughly 24 megajoules per kilogram.. The energy density of coal can also be expressed in kilowatt-hours, the units that electricity is most commonly sold in, per units of mass to estimate how much coal is required to power electrical appliances.One kilowatt-hour is 3.6 MJ, so the energy density of coal is 6.67 kW·h/kg.
