My textbook (Daniel v. Schroeder) says that the Clausius-Clapeyron formula is (for phase boundary between liquid and gas)

[tex] \frac{dP}{dT} = \frac{L}{T\left(V_{g} - V_{l} \right)} [/tex].

What is [itex]V_{l}[/itex] or [itex]V_{g}[/itex]? It's not volume. I looked on Wikipedia, they say that [itex]V_{g} - V_{l}[/itex] is the difference in specific volume of gas and liquid.

Specific volume is defined as [tex]\nu = \rho^{-1}[/tex].

My question is, is [itex]V_{l}[/itex] and [itex]V_{g}[/itex] specific volumes for gas and liquid, or I mean is it correct?

I want to ask just to be sure.

Thank you in advance for responding,
