Determination of specific heat Capacity of a solid by electrical method Introduction Thermal conductivity heat is transferred as a consequence of temperature difference between 2 bodies‚ heat energy passes form a hotter to the colder body. Specific heat capacity is the amount of heat energy required in joules to raise 1kg of a substance by 1 degree Celsius‚ different substances absorb heat energy at different rates not all substances require the same amount of heat energy to increase the internal
