4C40.10carbon dioxide4C40.10Watch carbon dioxide sublimate.
4C40.10carbon dioxideH-51Evaporation of "dry ice".
4C40.10sublimation of CO2Disc 15-18Small solid carbon dioxide flakes are generated by cooling a CO2 balloon in liquid nitrogen.
4C40.11carbon dioxideH-95Show chattering due to formation and escape of vapor.
4C40.12carbon dioxide rockerH-52Detect the evaporation of gas by the high pitched rocking motion of one end of an iron rod placed on "dry ice".
4C40.15blow up balloon with CO2PIRA 1000
4C40.15blow up a balloon with CO2H-97Attach a balloon to a test tube with dry ice and when the balloon is inflated immerse the tube in liquid air.
4C40.16change of volume with change of statHk-1Dry ice blows up a balloon.
4C40.20iodine26-5.8Place melted iodine crystals in a partially evacuated tube and heat.
4C40.30ammonium chloride26-5.7Heat ammonium chloride in a test tube and it evaporates without melting, coating the cool sides of the tube. ALSO- solidify CO2.
4C40.40camphorH-53Heat camphor in one end of a tube and the vapors will condense on the cooler end. Project.
4C40.50sublimation of ice and snowTPT 3(7),322Freeze water in a large dish, then cover portions with rectangles of aluminum foil. After three weeks, the uncovered areas have sublimed about a half inch.
