Thermodynamic Work: Find w P, V, T Not Constants

[thejinx0r]

Hi,

How can I find the thermodynamic work from
dw=Pdv

if P, Vand T are not constants?
what if I knew that dp/dv is a constant in this case?

You need to express P as a function of V first. Then you can evaluate the integral,

W = ∫ P dV​
