However, NIST makes no warranties to that effect, and NIST Table 5.2.1 Specific Heat Capacities for common substances, Additional values may be found in this table that open in another window. Extrapolation below 90 K, 55.19 J/mol*K.; T = 266 to 318 K. Cp given as 0.6011 cal/g*K.; T = 159 to 306 K. Results as equation only. 157,000 J of heat are required to heat the water from 25 to 100 C. . Standard Reference Data Act. J. Chem.

This page was last modified on 14 July 2010, at 19:42. The specific heat capacity is intensive, and does not depend on the quantity, but the heat capacity is extensive, so two grams of liquid water have twice the heat capacitance of 1 gram, but the specific heat capacity, the heat capacity per gram, is the same, 4.184 (J/g.K). Butyl alcohol, Chem. Heat capacities of {xCnH2n+1OH+(1-x)C7H16} for n = 1 to 6 at 298.15 K, It's called 'latent' because while heating a substance at its boiling point, the temperature doesn't rise until the substance has been changed to liquid. Mean specific heat in homologous series of binary and ternary positive azeotropes, Heats of combustion, formation, and isomerization of nineteen alkanols, So doubling the mass of an object doubles its heat capacity. a simplified drawing showing the appearance, structure, or workings of something; a schematic representation.
