How is specific heat capacity measured
WebThe SI unit for specific heat capacity is joule per kelvin per kilogram J kg⋅K, J⋅K −1 ⋅kg −1. 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).
