Essentially, dry ice is frozen CO2. The first report of what we now call dry ice came from the French chemist Charles Thilorier in 1834. In 324, the Drylee Corporation of America named the solid form of CO2 as Dry Ice, which is what it is popularly called today.At normal atmospheric pressure, CO2changes directly from solid to gas. It skips the liquid phase（阶段）which makes regular ice wet. Frozen CO2is also much colder than regular ice. But regular ice freezes at 32 degrees Fahrenheit, CO2 changes from gas to solid at -21.3 degrees Fahrenheit. This extremely cold temperature makes it very dangerous to handle with bare hands. It can cause frostbite in a very short period of time.Dry ice has been used for a variety of purposes throughout the past century. Its primary use is to refrigerate food when electrical refrigeration isnt available. Through the process of sublimation (when CO2 changes from solid to gas), it can maintain cold food for a long time.If youve ever been to a play and seen heavy fog on the ground, it is likely that you have seen dry ice in action. This effect can be achieved because CO2 is heavier than air, so evaporated （挥发的）CO2 will sink and accumulate on the ground.Another interesting use for this substance is to bait（诱杀）insects like mosquitoes. These insects have sensors which guide them to CO2. They find the high concentration of CO2 in dry ice quite attractive.Mars has long been a mystery for human beings. We have been looking for evidence of life on Mars. In the 360s scientists guessed that the polar ice cap of Mars was made of frozen CO2. More recent observations have shown that while the topmost layer consists of frozen CO2, the most of it is probably regular frozen water.1、Frozen CO2 gets its name of Dry Ice mainly becauseAit is very easy to make it dryBwe cant melt it and it doesnt get wetCit looks like ice at a low temperatureDit is solid like ice at -21.3 degrees Fahrenheit2、The underlined word frostbite in the second paragraph probably meansAthe shakes caused by coldBdamage caused by
