Constant volume and constant pressure heat capacities are very important in the calculation of many changes. The ratio Cp / CV = γ appears in many expressions as well (such as the relationship between pressure and volume along an adiabatic expansion.) It would be useful to derive an expression for …
WebIn a constant volume process, TdS = CVdT, so that T ( ∂ S ∂ P) V = C V ( ∂ T ∂ P) V. And in a constant pressure process, TdS = CPdT, so that (13.4.8) T ( ∂ S ∂ V) p = C P ( ∂ T ∂ V) P. Therefore (13.4.9) T d S = C V ( ∂ T ∂ P) V d P + C P ( ∂ T ∂ V) P d V. This is the third of the TdS equations. In summary, then, these are the three TdS equations:
WebFrom here, the Joule-Thompson coefficient defined like this is also zero for ideal gas. Another characteristic of ideal gas is the difference between Cp and Cv. It was the gas constant R before. Let’s derive this relationship here. Cp is (dH over dT) at constant P and Cv is (dU over dT) at constant v. Let’s express the (dH over dT) first. optometrist burnaby brentwoodWebThey just differ by nR. So the difference between the heat capacity at constant volume which is three halves nR, and the heat capacity at constant pressure which is five halves nR, is just Cp minus Cv which is nR, just nR, and if you wanted to take the difference between the molar heat capacities at constant volume and pressure, it would just be R. optometrist bremerton waWebThe minimum energy required to eject electrons from the surface is called the work function. The energy of the incident photon should be greater than the work function. Hence, the conclusion of the photoelectric effect is that the energy in light comes in small packets.
