Derive the equation for pv work
WebThere's the isometric process, also known as isochoric or isovolumetric, where the change in volume is 0, which meant, remember, that means no work can be done. The work was also 0 for an isometric process. And then there's the adiabatic process where no heat is allowed to flow into or out of the system. WebPV m= RT 2 41 + b V m + b V m! 2 + ::: 3 5 a T2V m = RT 2 41 + 1 V m b a RT3 + b V m! 2 + ::: 3 5 Then the second virial coe cient is given by B(T) = b a RT3 = 0 when T= a Rb 1=3 9. A certain gas obeys the equation of state P= RT V m b a (V m+ b)2 where aand bare numerical constants. Given the critical volume of the gas is V c= 5b, derive an ...
