Derive the equation for pv work

Webwhere the last equality follows from the ideal gas law pV = RTand our deriva-tion for the work of a polytropic process is complete. Next, in order to nd the heat of a polytropic process, we rst nd Uand use the rst law to nd q. Knowing that C V = R 1 we can write U= C V T= R(T 2 T 1) 1 Then we have q= U w= R(T 2 T 1) 1 R(T 2 T 1) n 1 = R(T 2 T 1 ... WebAug 29, 2024 · Explanation: Let us look at a typical PV diagram.

WebThere's the isometric process, also known as isochoric or isovolumetric, where the change in volume is 0, which meant, remember, that means no work can be done. The work was also 0 for an isometric process. And then there's the adiabatic process where no heat is allowed to flow into or out of the system.

WebNow, if the volume is increasing on the isobaric graph, that would result in a positive deltaV and using the equation Wby = PdV, Work done BY the gas [Wby] would be postive. When you plug in this +Wby into the First Law of Thermodynamics equation (dU=Q+Won), the Work would become negative since Won = - Wby giving us dU=Q + (-Wby). WebH = E + PV (at constant pressure) Substituting the first law of thermodynamics into this equation gives the following result. H = ( qp + w) + PV Assuming that the only work done by the reaction is work of expansion gives an equation in which the PV terms cancel.
