Homework Statement
A liter of air, initially at room temperature and atmospheric pressure, is heated at constant pressure until it doubles in volume. Calculate the increase in its entropy during this process.
so Ti= 300K, Volume which is 2Vi=Vf; Pressure is constant
Homework Equations
ΔS @constant pressure is = ∫Cp/T dT (where Ti -> Tf
The Attempt at a Solution
so since I don't know what T is but I know how the volume changes is there a way I can relate it? is it just PV=nkT so use V as an analog to gauge the proportional change in T? so would that give me something like Cp*Ln[2]?
