Adiabatic: $P{V}^{\gamma }=$ const, $T{V}^{\gamma -1}=$ const, $P^{1-\gamma }{T}^{\gamma }=$ const. $P\propto T^{\gamma /(\gamma -1)}$ (increasing, convex): $\mathrm{A}\to \mathrm{R}.V\propto T^{-1/(\gamma -1)}$ (decreasing, convex): $\mathrm{B}\to \mathrm{P}$. $P\propto V^{-\gamma }$ (decreasing, convex): $\mathrm{C}\to \mathrm{P}.P\propto U^{\gamma /(\gamma -1)}$ since $U\propto T$ (increasing, convex): D→R.
