A number of materials contract on heating within certain temperature ranges; this is usually called negative thermal expansion, rather than "thermal contraction".For example, the coefficient of thermal expansion of water drops to zero as it is cooled to 3.983 °C (39.169 °F) and then becomes negative below this temperature; this means that water has a maximum density at this temperature, and ...
For a single component system, the "standard" three parameters are the isothermal compressibility , the specific heat at constant pressure , and the coefficient of thermal expansion . For example, the following equations are true:

When matter is transferred into a system, the internal energy and potential energy associated with it are transferred into the new combined system. ( u Δ M ) i n = Δ U s y s t e m {\displaystyle \left(u\,\Delta M\right)_{\rm {in}}=\Delta U_{\rm {system}}} where u denotes the internal energy per unit mass of the transferred matter, as measured ...
To distinguish these two thermal expansion equations of state, the latter one is called pressure-dependent thermal expansion equation of state. To deveop the pressure-dependent thermal expansion equation of state, in an compression process at room temperature from (V 0, T 0, P 0) to (V 1, T 0,P 1), a general form of volume is expressed as
