During a small change in the … WebAug 28, 2024 · Cp and Cv are specific heats at constant pressure and constant volume respectively. It is observed that Cp−Cv =a for hydrogen gas C p−Cv=b for nitrogen …
WebC P > C V C P is greater than C V because when a gas is heated at constant volume, no external work is done and so the heat supplied is consumed only in increasing the internal energy of a gas. But if the gas is heated at constant pressure, the gas expands against the external pressure so does some external work. in this case the heat is used up in … WebJun 4, 2015 · At constant volume, all the heat that goes into the system goes into raising the temperature of the system, and no external work is done. At constant pressure, some of …
WebApr 3, 2024 · Because the gas is heated at a consistent rate, the heat is simply given to raise the temperature of the gas.As we heat the gas under constant pressure, the … WebQuestion: question 6 a) Explain physically why Cp is higher than Cv for an ideal gas. (1 mark) b) Demonstrate that for an ideal gas: Cp – Cv = R. (1 mark) c) Knowing that for an ideal gas internal energy is only a function of temperature, show then that the enthalpy is also only a function of temperature.
