Standard enthalpy of formation, Gibbs energy of formation, entropy and molar heat capacity of organic substances
ΔH°f : The standard enthalpy of formation at 25°C (298,15 K) for 1 mol of the substance in its given state (g= gas and l= liquide) from its elements in their standard state (stable forms at 1 bar and 25°C)
ΔG°f : The standard Gibbs free energy of formation at 25°C (298,15 K) for 1 mol of the substance in its given state (g= gas and l= liquide) from its elements in their standard state (stable forms at 1 bar and 25°C)
S°: The standard entropy for 1 mol of the substance in its given state (g= gas and l= liquide) at 1 bar and 25°C
Cp : The standard molar specific heat capacity of the substance in its given state (g= gas and l= liquide) at constant pressure and 25°C

See also Standard state and enthalpy of formation, Gibbs free energy of formation, entropy and heat capacity for ΔH°f, ΔG°f, S° and Cp for more than 370 inorganic substances and gases , common liquids and fluids , food and foodstuff , metals and semimetals , common solids and other common substances for tabulated values of specific heat capacity, cp .
For conversion of units, use the Specific heat online unit converter.
The specific heat capacity can be calculated from the molar heat capacity, and vise versa:
cp = Cp / M and
Cp = cp . M
where
cp = specific heat capacity
Cp = molar heat capacity
M = molar weight of the actual substance (g/mol).
