20.2.1 Thermal properties: overview

The following properties describe the thermal behavior of a material and can be used in heat transfer and thermal stress analyses (see “Heat transfer analysis procedures: overview,” Section 6.5.1):

**Thermal conductivity**: When heat flows by conduction, the thermal conductivity must be defined (“Conductivity,” Section 20.2.2).

**Specific heat**: In transient heat transfer analyses as well as adiabatic stress analyses the specific heat of a material must be defined (“Specific heat,” Section 20.2.3).

**Latent heat**: When a material changes phase, the change in internal energy can be significant. The amount of energy liberated or absorbed can be defined by specifying a latent heat for each phase change a material undergoes (“Latent heat,” Section 20.2.4).
