It indicates the substance\u2019s ability to store thermal energy and equals the amount of heat that must be added to one gram of the substance in order to raise its temperature by one Kelvin. This process should not result in a 1st order phase transition (e.g. melting), since, in this case, the Cp can be infinitely large and therefore cannot be measured.<\/p><p><strong>The SI unit of the specific heat capacity is kilojoules per kilogram times Kelvin [J\/g*K)].<\/strong><\/p><p>In general, specific heat capacity can be differentiated as<strong> isobaric (Cp at constant pressure) and isochoric (CV, at constant volume)<\/strong> based on the heat input. While at constant volume the amount of heat is completely used to increase the temperature; at constant pressure, only part of the heat is required for the volume change. This must be taken into account when measuring gases and vapors.<\/p><p>With a large Cp value, a certain amount of heat only leads to a slight increase in temperature; if the value is small, the same amount of heat can cause a greater temperature increase.
