For example, the molar heat capacity of water (at constant pressure) is 75 J/ (mol.K) implies that 75 J of heat energy is required to raise the temperature of 1 mole of water by 1 K. In general ...
WebSummary. For an ideal gas, the molar capacity at constant pressure Cp C p is given by Cp = CV +R = dR/2+ R C p = C V + R = d R / 2 + R, where d is the number of degrees of freedom of each molecule/entity in the system. A real gas has a specific heat close to but a little bit higher than that of the corresponding ideal gas with Cp ≃CV +R. http://api.3m.com/what+is+the+heat+capacity+of+ethanol
