Difference in Cp and Cv
Difference in Cp and Cv From the definitions of Cp and Cv, PV dq dq Cp Cv dT dT −=− (1) Substitution of the definition of entropy gives PV SS Cp Cv T TT ⎡⎤∂∂ −=⎢− ⎣⎦∂∂ ⎥ (2) These partials are converted from the total differential obtained from Sf= (,TV) VT SS dS dT dV TV ∂∂ =+ ∂∂, which when divided by dT at

cp cv nR Enthalpy • Enthalpy is the amount of heat content used or released in a system at constant pressure Usually defined as a thermodynamic potential as a thermodynamic potential, designated by the letter "H", that consists of the internal energy of the system (U) plus the product of pressure (p) and volume (V) of the system
