Equations of thermal equilibrium along coronal magnetic loops are solved in the absence and presence of gravity. Without gravity, four categories of loop are found: hot, cool, hot-cool, and warm. Which categories exist depends on two parameters involving the heating, the loop length and the footpoint pressure. Including gravity, the longer hot loops suffer a decrease in their summit temperatures. The hot-cool loops are restricted to a very small range of lengths. A hot-cool arcade can still exist if either the coronal heating or the loop footpoint pressure varies. When the cross sectional area does not vary from footpoint to summit, hot-cool loops may exist only for unrealistically low gravity. However, causing the cross sectional area to vary may allow hot-cool loops to exist for realistic gravity.
