Gas Law Derivatives

[apricimo]

Can someone explain what the difference is in taking the derivative with respect to P of PV=nRT vs V=nRT/P ? T is kept as a constant.

PV=nRT; energy form, classical ideal gas equation, PV=Constant and constant value is nRT

V=nRT/T; volume form, ideal gas state equation

state equation P(T,V), P(T, lo)

state equation, special, V(T,P) Virial equation, volume form

I think I am too ignorant for this explanation. Can you expand on this in more detail. Thank you

What's the derivative of an equation supposed to be, anyhow?

What is the main point you want to know about?

That represents all tendency about those equations.

The difference in taking the derivatives... Thought that was clear

I think this site state you the whole thing what you know about.

In the state equation, P(pressure) is key factor. To get more precise value about the real gas many equations are developed.
