Web1 day ago · For a closed system, the first law is written as −. Σ Q = Σ W. But this is only valid for a closed system which is undergoing a cycle. For a process it can be written as −. Q 1 − 2 = U + W 1 − 2. Before we can start modelling these one should know how to model work and heat for different processes. So let us do that first. WebThe work done on the system equals the final pressure times the final volume minus the initial pressure times the initial volume divided by the polytropic index minus 1. The heat …
WebMay 13, 2024 · 1. For a polytropic process, We say that Work done by the gas is. W = Δ ( P V) 1 − r = P 2 V 2 − P 1 V 1 1 − r. So, Following First law of thermodynamics, Q = W + Δ U.
