Phenomenon and application of sublimation and sublimation
1. ** Phenomenon of sublimation ** - [Description: The phenomenon of a substance changing from a solid state to a gaseous state is called sublimation.] - Common phenomenon: - When heating the iodines, purplish-red iodines vapor could be seen. - The mothflake used to prevent insects in the wardrobe would slowly shrink until it disappeared. - The frozen clothes dried up, and the ice directly turned into steam without going through the liquid process. - The snow didn't melt, but it became smaller. The solid snow directly turned into gas. - The tungsten of the lamp became thinner, and the tungsten of the lamp turned from solid to gas. - The solid fragrance disappeared, and the solid fragrance turned into gas. - The dry ice sublimated, and the solid carbon dioxide directly turned into gaseous carbon dioxide. - Sublimation conditions: Generally, at any temperature, sublimation will occur on the surface of any solid. 2. ** Condensation Phenomenon ** - [Description: The phenomenon of a substance changing from a gaseous state to a solid state is called sublimation.] - Common phenomenon: - In winter, beautiful ice flowers would appear on the glass. This was because the indoor temperature was higher than the outdoor temperature. The water vapor in the air would condense into small ice crystals attached to the inner surface of the glass when it met the very cold glass. - The formation of frost was the condensation of water vapor in the air when it cooled. - Rime was also formed by the condensation of water vapor in the air. - The light bulb would turn black after a long time because the tungsten vapor would condense on the inner wall of the light bulb when it was cold. - Sublimation conditions: The vapor of the substance must reach a certain concentration and the temperature must drop below the freezing point of the substance to occur. 3. ** The application of sublimation and sublimation ** - ** Sublimation Heat Absorption Technique **: - Artificial rainfall: First, the sublimation and cooling of dry ice; second, the condensation of water vapor into small ice crystals; third, the melting of small ice crystals into small water droplets when they fall and meet the hot airflow. The small water droplets become bigger and bigger, and the water droplets fall to the ground to form rain. - Stage Smoke: The dry ice powder is sprayed onto the stage and quickly sublimates and lowers the temperature, causing the water vapor in the air to condense into small water droplets to create a "white fog" to enhance the atmosphere. - [Food Storage, Medical Surgery: Solid carbon dioxide can be directly sublimated into gaseous carbon dioxide. At the same time, it absorbs a large amount of heat without leaving any residue.] Using this characteristic, it could be used as a strong cryogen, used to store food, or used in medical research. In modern medicine,"cryotherpy" was to place dry ice (solid carbon dioxide) on some tissues and use the dry ice to sublimate and absorb heat to quickly cool down, causing the tissues to be necrotic. - The sublimation heat release did not directly mention special large-scale applications, but it reflected its principle in the formation of some natural phenomena, such as the formation of frost, ice flowers, and rime. - Sublimation absorbs heat and has a cooling effect, while sublimation emits heat. Sublimation and sublimation are the opposite processes. When analyzing the phenomenon of state change, one had to understand the initial state and final state of the state change, as well as the conditions in the process of change.
