Derive an expression for the molar specific heat at constant volume of the mixture. Expression must be in terms of n_1, n_2, and the gas constant R. I know that the molar specific heat of the entire mixture is Q = C_v(n_1+n_2)*delta(T). and my physics professor told me ...
The internal energy, U, may be related to the specific heat at constant volume (cv). Furthermore, if the fluid is assumed to be incompressible, the specific heats at constant pressure (cp) and constant volume are equal. Applying these conditions and assuming that the thermal conductivity is ...
Analytical expressions for specific heat at constant pressure were developed empirically as polynomials. Stoichiometric equilibrium models for gasifiers mainly adopt the expressions exposed by Çengel & Boles (2002) [97], but other expressions can be used as shown in Table 8 which exposes the format...
The experimental EoS for this phase shows that its specific heat at constant volume ( C ) is significantly smaller than that based on a harmonic model. Also, the sign of which is normally negative in the quasi-harmonic approximation, is unexpectedly positive. The thermodynamic Grüneisen parameter...

The amount of heat absorbed (or released), i.e., the enthalpy change associated with this process. The enthalpy (H) of a system is the measure of its internal energy while pressure and volume are constant, and enthalpy change {eq}(\Delta H) {/eq} (also called enthalpy of the reaction...
engineering interest reduce to this classic case. As we heat the material from the left surface, the entire volume of material gets gradually, but nonuniformly, hotter. There is also radiative cooling and some free convection from the left side, approximated as a constant heat transfer ...
where, kx, ky, kz = thermal conductivity coefficients,θ = temperature, Q = heat generation per unit volume, ρ = density, and cp = specific heat at constant pressure. If we focus our attention to the two-dimensional (∂/∂z = 0) steady-state (∂/∂t = 0) problem, such as...
