Specific heat constant pressure equation

WebThe specific heat capacity can be calculated from the molar heat capacity, and vise versa: cp = Cp / M and Cp = cp . M where cp = specific heat capacity Cp = molar heat capacity M = molar weight of the actual substance (g/mol). Example: Methanol (with molecular formula CH3OH) has a molar heat capacity, C p, of 81.1 J/ (mol K). International system The SI unit for specific heat capacity is joule per kelvin per kilogram J/kg⋅K, J⋅K ⋅kg . Since an increment of temperature of one degree Celsius is the same as an increment of one kelvin, that is the same as joule per degree Celsius per kilogram: J/(kg⋅°C).
