In thermodynamics, the specific heat capacity (symbol c) of a substance is the heat capacity of a sample of the substance divided by the mass of the sample, also sometimes referred to as massic heat capacity. Informally, it is the amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in temperature. The SI unit of specific heat capacity is joule per kelvin per kilogram, J⋅kg ⋅K . For example, the heat required to raise the temp… WebC p,gas: Constant pressure heat capacity of gas: S° gas Entropy of gas at standard conditions: S° gas,1 bar Entropy of gas at standard conditions (1 bar) Δ c H° gas: Enthalpy of combustion of gas at standard conditions
