WebSpecific heat is closely related to the concept of heat capacity. Heat capacity is the amount of heat necessary to change the temperature of a substance by 1.00 °C. In equation form, heat capacity C is C = m c, where m is mass and c is specific heat. Note that heat capacity is the same as specific heat, but without any dependence on mass. WebThe Molar specific heat of a solid or liquid of a material is the heat that you provide to raise the temperature of one mole of solid or liquid through 1K or 1° C. We represent it as C. Its unit is J mol-1K-1. So, to raise the …

The original theory proposed by Einstein in 1907 has great historical relevance. The heat capacity of solids as predicted by the empirical Dulong–Petit law was required by classical mechanics, the specific heat of solids should be independent of temperature.But experiments at low temperatures showed that the heat capacity … Web8 Answers. For metals there is a connection between the thermal conductivity and electric conductivity (Wiedemann–Franz law). However specific heat is not directly related. This is because electric and thermal conductivity are due to the electrons, however the specific heat is mostly due to the ion vibrations (phonons). cp railroads
