Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase. Sublimation is an endothermic phase transition that occurs at temperatures and pressures below a substance's triple point in its phase diagram.
Why does peripheral vasoconstriction happen? Peripheral vasoconstriction occurs to allow the body to retain core heat for longer as protection against hypothermia by allowing the skin to act as an insulating layer between core organs and the water. It also allows more oxygen to be delivered to important and oxygen-sensitive organs such as heart and brain.
