	Volumetric heat capacity - Wikipedia, the free encyclopedia
		Volumetric heat capacity (VHC) describes the ability of a given volume of a substance to store heat while undergoing a given temperature change, but without undergoing a phase change.
		It is different from specific heat capacity in that the VHC depends on the volume of the material, while the specific heat is based on the mass of the material.
		The volumetric heat capacity is defined as having SI units of J/(m³·K).

		The specific heat capacity (symbol c or s, also called specific heat) of a substance is defined as heat capacity per unit mass.
		Temperature: Measuring the heat capacity of water produces different results if the starting point is 20 Â°C rather than 60 Â°C. Therefore the temperature at which the measurement was conducted must be specified for the value to be useful.
		Two distinct capacities can also be defined for liquids and solids, however the difference between the two is generally no worth considering: liquids and solids are nearly incompressible, so that their thermodynamic behavior is not significantly affected by pressure.

	Station Information - Specific heat capacity
		Specific heat capacity is the slope (derivative) of the internal energy due to random motion of atoms in a sample as a function of temperature, normalized by dividing by the mass of the sample.
		Because the internal energy curve is normally almost linear, it can by approximated by measuring the heat required to raise the temperature of 1 kg of a substance by 1 °C (or one Kelvin).
		If a fluid has stronger intermolecular forces (such as hydrogen bonding in water) then the heat capacity is likely to be higher.
