WebH=U+pV. The above total enthalpy equation indicates that the enthalpy (H) is the sum of the total internal energy (U) and the product of the pressure (p) and volume (V) of the system. When the pressure is assumed constant, the term pV is the work required in the system. Given the extensive nature of enthalpy, mass, volume, or pressure changes ... WebFor a temperature change at constant volume, dV = 0 and, by definition of heat capacity, d ′ QV = CV dT. (31) The above equation then gives immediately (32) for the heat capacity at constant volume, showing that the change in internal energy at constant volume is due entirely to the heat absorbed. To find a corresponding expression for CP ...

WebA. Internal Energy U In Thermodynamics, the total energy E of our system (as described by an empirical force ﬁeld) is called internal energy U. U is a state function, which means, that the energy of a system depends only on the values of its parameters, e.g. T and V, and not on the path in the parameters space, which led to the actual state.
