Importance of specific heat
WitrynaThe heat supply under constant pressure simultaneously causes an increase in volume, for which a part of the energy is used up. The distinction is of importance only in the consideration of gases and vapors. The specific heat capacity of solids is used primarily in the construction industry for the assessment of the behavior of building material. WitrynaSpecific heat, or specific heat capacity, is a property related to internal energy that is very important in thermodynamics. The intensive properties cv and cp are defined for pure, simple compressible substances as partial derivatives of the internal energy u (T, v) and enthalpy h (T, p), respectively:

Witryna11 mar 2024 · At 15°C, the precise value for the specific heat of water is 4.184 J K –1 g –1, and at other temperatures it varies from 4.178 to 4.219 J K –1 g –1. Note that the specific heat has units of g (not the base unit kg), and that since the Centigrade and kelvin scales have identical graduations, either o C or K may be used.
