Understanding Heat Density

Heat density, also known as volumetric heat density or heat energy density, is the amount of heat energy stored per unit volume of a substance. It is a measure of how much thermal energy can be contained in a given space.

The SI unit for heat density is Joules per cubic meter (J/m³).
