Suppose you keep \(W\) and \(T_{\text {out }}\) in the reversible process of Figure 21.24a fixed but increase \(T_{\mathrm{in}}\). Do the magnitudes of these quantities increase, decrease, or stay the same:

(a) \(\Delta S\) associated with the upgrade,

(b) \(\Delta S\) associated with the degradation,

(c) \(Q_{\text {in }}\) ?
