It is not uncommon for the night sky temperature in desert regions to drop to \(-40^{\circ} \mathrm{C}\). If the ambient air temperature is \(20^{\circ} \mathrm{C}\) and the convection coefficient for still air conditions is approximately \(5 \mathrm{~W} / \mathrm{m}^{2} \cdot \mathrm{K}\), can a shallow pan of water freeze? Can the water freeze under windy conditions with \(\bar{h}=10 \mathrm{~W} / \mathrm{m}^{2} \cdot \mathrm{K}\) ?
