### Formulas

Hello!

There are many different formulas between chapters 8 and 9, and I am confused specifically as to when we use each one.

Would someone be willing to outline the various formulas and the circumstances for which they are applicable?

In case anyone sees this post: Who knows how you get P(delta-V)=delta-nRT?

### Re: Formulas

This equation comes from the ideal gas law, PV=nRT. This formula can also be translated to P(delta-V)=delta-nRT, which basically says that the pressure times the change in volume is equivalent to the change in moles times R and T.
