A helpful equation sheet

[Chem_Mod]

This is an equation sheet that one of the TAs made up. The chart is only applicable to ideal gases. Please respond if there are any errors (I may have made a typo or 2). Remember that this may not have every equation for every scenario and that you will still need to know how and when to use these equations. Also, not all of these will be on the equation sheet given, so you should know how to derive these or where they come from.

Could someone explain when to use Cp or Cv? Is Cp used when the pressure is constant, while Cv is used when the volume is constant? Thank you!

You got it, also remember how to calculate it when presented with an ideal gas, although it is on the formula sheet.

Thank you guys so much!!

Why is DeltaU for constant pressure being calculated using C_v? In order words, why is the change in internal energy for a system under constant pressure (DeltaU) using the C_v value in its calculations? Shouldn't DeltaU = q + w?
