WebMar 11, 2024 · Specific heat tells you the amount of energy needed to raise each unit one degree. For example, it takes .417 Joules to raise 1 gram of water 1 degree Celsius. So, water's specific heat is .417 J/C per gram. The specific heat of a material is constant. That means that all pure water has the same specific heat-- .417 J/C. WebThe values for most minerals present in the soil are between 0.18 to 0.20 cal/gm. 2. Heat capacity (volume specific heat): It is the amount of heat required to raise the temperature of one cubic centimeter substance by 1 0C .Most soils have a heat capacity in the range of 0.3 to 0.6 cal/Cm3. 3. Thermal conductivity:
