apricimo Posted January 26, 2011 Share Posted January 26, 2011 (edited) 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. Edited January 26, 2011 by apricimo Link to comment Share on other sites More sharing options...
alpha2cen Posted January 27, 2011 Share Posted January 27, 2011 (edited) 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 Edited January 27, 2011 by alpha2cen Link to comment Share on other sites More sharing options...
apricimo Posted February 3, 2011 Author Share Posted February 3, 2011 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 Link to comment Share on other sites More sharing options...
timo Posted February 3, 2011 Share Posted February 3, 2011 What's the derivative of an equation supposed to be, anyhow? Link to comment Share on other sites More sharing options...

Thank you What is the main point you want to know about? That represents all tendency about those equations. Link to comment Share on other sites More sharing options...

alpha2cen Posted February 5, 2011 Share Posted February 5, 2011 I think this site state you the whole thing what you know about. http://en.wikipedia.org/wiki/Equation_of_state In the state equation, P(pressure) is key factor. To get more precise value about the real gas many equations are developed. Link to comment Share on other sites More sharing options...
