PdV + VdP = n(Cp – Cv)dT

PdV + VdP = n(Cp – Cv)dT

---------------------------------------------------

PV = nRT

---> P and V are functions of T

Use the product rule to find the derivative

Take the derivatiove, use the product rule

PdV + VdP = nRdT

Cp – Cv = R 이므로,

( 참고 https://ywpop.tistory.com/23367 )

PdV + VdP = n(Cp – Cv)dT
