Best Answer: In 1835 the French chemist Charles Thilorier published the first account of dry ice. Upon opening the lid of a large cylinder containing liquid carbon dioxide he noted much of the carbon dioxide rapidly evaporated leaving solid dry ice in the container. Throughout the next 60 years, dry ice was observed and tested by scientists.So dry ice mainly was named dry ice because the carbon dioxide had evaporated into the air without making a watery mess, and that is how it got its name. PragmaticAlien is correct. Frozen CO2 goes directly from solid to gas.
So, how long does dry ice last? The following table for how long dry ice lasts is based on an average 5 pound brick of dry ice that remains whole (not broken into pieces). Because of its short shelf life, dry ice should be purchased as close to when you need it as possible.f course, dry ice lasts for a shorter period of time if it is not stored properly. It subliminates (turns from solid form to gas form) at a rate of about 5-10 pounds every 24 hours. So, if you need about 15 pounds of dry ice for the next day you need to buy 20-25 pounds the day before.
