WebJan 15, 2024 · The work of expansion can be depicted graphically as the area under the p-V curve depicting the expansion. Comparing examples \(\PageIndex{1}\) and \(3.1.2\), for which the initial and final volumes were the same, and the constant external pressure of the irreversible expansion was the same as the final pressure of the reversible expansion, … WebSep 12, 2024 · A quasi-static, adiabatic expansion of an ideal gas is represented in Figure \(\PageIndex{2}\), which shows an insulated cylinder that contains 1 mol of an ideal gas. The gas is made to expand quasi-statically by removing one grain of sand at a time from the top of the piston. When the gas expands by \(dV\), the change in its temperature is \(dT\).

WebJan 30, 2024 · Rearranging this equation a bit we get: Q = ΔU + W. Next, since pressure is equal to W ΔV, it can be denoted as: Q = ΔU + pΔV. Now, the ideal gas law can be applied (PV=nRΔT) and since pressure is constant: Q = ΔU + nRΔT. For the next step, we will assume that this number of moles of gas stays constant throughout this process: Webchange of state of perfect gas, the ratio between initial and final states. piVi/Ti = pfVf/Tf. this is given on equation ... for monatomic perfect gas, is equal to ∆S = ∆S= Cv ln Tf/Ti for monatomic perfect gas, ∆S= 3/2 nR ln Tf/Ti. at constant pressure, ∆S = which, for monatomic perfect gas, is equal to ∆S = ∆S= Cp ln Tf/Ti for ...
