The table of specific heat capacities gives the volumetric heat capacity as well as the specific heat capacity of some substances and engineering materials, and (when applicable) the molar heat capacity. Generally, the most notable constant parameter is the volumetric heat capacity (at least for solids) which is around the value of 3 megajoule per cubic meter per kelvin: Webcp = specific heat (kJ/kg K, kJ/kg C°) dt = temperature difference (K, C°) Example - Heating Carbon Steel 2 kg of carbon steel is heated from 20 oC to 100 oC. The specific heat of carbon steel is 0.49 kJ/kgC° and the heat required can be calculated as q = (0.49 kJ/kg oC) (2 kg) ( (100 oC) - (20 oC)) = 78.4 (kJ) Sponsored Links Related Topics WebThe basic specific heat unit in the SI system is joule per kilogram per kelvin: J k g × K. … important physical features in russia
