Skipping liquids Sublimation

At pressures below the triple point, such as in outer space where the pressure is low, liquid water cannot exist ice skips the liquid stage and becomes gaseous on heating, in a process known as sublimation. 

Snow sublimation happens particularly often in the western United States, where warm, dry winds often blow after an intense cold spell. When these warm, dry winds blow over an area covered in snow, the snow sublimates directly to a gas, skipping the liquid phase entirely. In some areas, this wind is known as the Chinook Wind (Chinook is a Native American word that means snow eater. 8) Although sublimation plays a less vital role in the planets water cycle than some other phase changes, such as evaporation and condensation, it still serves to move water around Earth. 

Deposition is the opposite of sublimation. It occurs when a gas changes into a solid. In both of these phase changes, the liquid state of matter is skipped altogether. Instead of a solid melting into a liquid and then becoming a gas, as is more common, the solid skips directly to the gaseous state and vice versa. 

During condensation, gaseous particles slow down and are overcome by the intermolecular forces at work in liquids. During sublimation and deposition, temperature and pressure conditions are so extreme that the liquid phase simply gets skipped. 

At the triple point pressure, liquid water cannot exist without a change in temperature. Instead, heated ice skips the liquid stage and changes directly from a solid to a gas in the sublimation phase... 

To get the water out of food without using heat, freeze-drying skips the liquid phase of water entirely. First, all the water in food is frozen solid in place. Then sublimation is used to convert the solid water into water vapor so it can be extracted without changing the shape or texture of the food. 

There is a AH for the process of sublimation, called the latent heat of sublimation (heat of sublimation). Sublimation is the conversion from the solid state to the gaseous physical state, skipping the liquid state. Elemental iodine, I2, and C02 are substances that sublime at 1 atm pressure. 

Chemical properties 1-131 can change directly from a solid to a gas, skipping the liquid phase, in a process called sublimation. 1-131 dissolves easily in water or alcohol and is highly reactive.
