Ideal Gases as a model/ entropy where to start.
(a) Using ideal gases as a model, show that the increase of entropy of n moles of a gas heated at constant pressure from a temperature T1 to a temperature T2 is
$\displaystyle ΔS = nCpln(T2/T1) $
(b) Show that the increase of entropy of a gas heated at constant volume from a temperature T1 to a temperature T2 is $\displaystyle ΔS = nCvln(T2/T1) $
I am aware that I am supposed to show some work but I do not have a clue where to start this problem. A point in the right direction(equations to use) or a walk through would be greatly appreciated. Thank you.
