폴리트로픽 과정은 pv^n=상수 로 표시할 수 있는 모든 과정(이상과정, 실제과정)을
총칭합니다. 한 예로 등온과정이라면 지수 n=1로 표시할 수 있지요?
등온, 등압, 등적, 단열과정이 아닌 그밖의 과정에서도 n 값이 상수로 표시될
수 있는 경우가 있는데, 이때는 실험으로 구하게 됩니다. p, v에 대한 로그 그래프를
그려보아 직선으로 표시할 수 있으면 폴리트로픽 과정이며, 그때의 기울기가 바로
폴리트로픽 지수 n이 됩니다.

>시스템내에 이상기체 실제 과정시 비가역요소를 고려한 폴리트로피과정에 대해 궁금한것이 있습니다.
>폴리트로피 과정은 정적.정압.등온.단열 과정에 따라 폴리트로피 지수를 결정하게 되는데 이 결정기준이 무엇인지....? 예를 들어 피스톤(밀폐시스템)내에서 초기 상태량 값 p,T,v값을 갖는 이상기체가 외부에서 열을 받고 외부에 일을 하여 그값들이 모두 변했다면(p,T,v).....이런 경우는 정적,등온,정압 두 아니고..그렇다구 열을 받았는데 단열과정이라 할수도 없구.....이런 실제 과정에서는 어떻게 해석을 해야 할지???
