Document Summary

Heat capacity is a property that is indicative of a material"s ability to absorb heat from the external surroundings (j/mol-k, or cal/mol-k). The magnitude of cp is almost always greater than cv. In most solids the principal mode of thermal energy assimilation is by the increase in vibrational energy of the atoms. Debye temperature d, cv levels off and becomes essentially independent of temperature at a value of approximately 3r, electronic contribution are minor relative to the magnitude of the vibrational contribution. A large spike is produced on the heat capacity-versus-temperature curve at the temperature of this transformation for ferromagnetic coefficient of thermal expansion is in (deg c)^-1. For materials in which the thermal expansion is isotropic, v is approximately 3 l. Ceramic materials that are to be subjected to temperature changes must have coefficients of thermal expansion that are relatively low, and in addition, isotropic for there to be no thermal shock.
