Specific Heat of Selected Elements

TABLE 2-153 Heat Capacities of Inorganic and Organic Liquids [J/(kmol K)] 

Dimethyl sulfide Dimethyl sulfoxide Dimethyl terephthalate 1,4-Dioxane Diphenyl ether Dipropyl amine Dodecane Eicosane 

3- Heptanone 2-Heptanone 1-Heptene Heptyl mercaptan 1-Heptyne Hexadecane Hexanal Hexane Hexanoic acid 

For the 11 substances, ammonia, 1,2-butanediol, 1,3-bntanediol, carbon monoxide, 1,1-diflnoroethane, ethane, heptane, hydrogen, hydrogen snlfide, methane, and propane, the liquid heat capacity CpL is calculated with Eq. (2) below. For all other compounds, Eq. (1) is nsed. For benzene, fluorine, and helinm, two sets of constants are given for Eq. (1) that cover different temperature ranges, as shown in the table. 

The number of digits provided for values at T, and was chosen for nniformity of appearance and formatting these do not represent the uncertainties of the physical qnantities, bnt are the result of calculations from the standard thermophysical property formnlations within a fixed format.
