Explain why cp cv
WebFAQ's on Heat Capacity. Q 1. Can the heat capacity of any substance be zero? Answer: Zero heat capacity of any substance means an infinitesimally small amount of heat will increase the temperature by an infinitely large amount because it has very less internal degrees of freedom into which it can channel the absorbed energy or heat.The smaller … WebFeb 22, 2024 · Cv and Cp denote the molar specific heat capacities of a gas at constant volume and constant pressure, respectively.

WebJun 25, 2024 · Summary Cp-Cv = R In thermodynamics, our objective is to utilize internal energy as efficiently as possible. Cp and Cv are just two indicators. WebSep 12, 2024 · Estimate the heat capacities of metals using a model based on degrees of freedom. In the chapter on temperature and heat, we defined the specific heat capacity with the equation Q = mcΔT, or c = (1 / m)Q / ΔT. However, the properties of an ideal gas depend directly on the number of moles in a sample, so here we define specific heat …
WebAug 21, 2015 · Let's see the actual concept. Cv is heat capacity at constant volume. Constant volume has no direct meaning in heat retaining capacity. Constant volume indirectly means work done is prevented. In this situation, all the heat, if added, is contained within the system volume. On the other case, Cp is heat capacity at constant pressure. WebJan 16, 2024 · Cp − CV = TVα2 κT And this is a completely general result since the only assumptions made were those that allowed us to use the combined first and second laws …
