A Bit More First Law:
Cp > Cv always. For an ideal gas, Cp
- Cv = nR. You should know how to derive
this. The last important pathway we will talk about is when q =
0. This is called an adiabatic path. By setting deltaU
= w, we derived the following equation:Cv/nR ln (Tf/Ti) = ln (Vi/Vf)We then manipulated this equation further to put it in a form that is easier to solve plug-and-chug style, but this is the important result. |
