Thermophysical properties
The molar heat capacity of cobalt (the ratio of heat capacity to the amount of material) is 24.8 J / (K · mol). This is a physical quantity that is numerically equal to the amount of heat that must be transferred to one mole of a given substance in order to change its temperature by one. The molar heat capacity is usually denoted by the symbol
