ICE

ANATOMY W OFDATA.COM THE CRYSTALLINE SOLID FORMED 7% WHEN WATER FREEZES COVERS 10 10% PER CENT OF THE EARTH'S LAND MASS, AND FORMS SEVEN PER CENT OF THE OCEANS. THE PROCESS OF FREEZING// AIR BUBBLES TRAPPED IN WATER REFRACT THE LIGHT AND GIVE ICE CLOUDY LOOK. WATER EXPANDS AS IT THIS IS COMMON IN HOME -MADE FREEZES, AND FREEZES FROM THE OUTSIDE IN, SO THE AIR IS PUSHED TO THE CENTRE OF THE ICE CUBES, BECAUSE THE WATER FROM THE TAP BECOMES AERATED AS IT POURS. CUBE, WHICH IS WHY ICE CUBES TEND TO OPAQUE HAVE PARTICULARLY OPAQUE CENTRES. EXPANDS PUSHED AIR IS GLASS ICE WATER DOESN’T ALWAYS FREEZE AT oc (32F) 0°C -42°C NUCLEI SUPERCOOLING IT NEEDS SOMETHING FOR ITS MOLECULES TO IF THERE ARE NONE OF THESE, YOU CAN GET LATCH ON TO. ICE CRYSTALS FORM AROUND “NUCLEI", SUCH AS SMALL PARTICLES OF DUST. THE TEMPERATURE OF WATER DOWN TO -42C (-44F) BEFORE IT FREEZES IN A PROCESS KNOWN AS “SUPERCOOLING". AND TRANSFORMS INTO A CHAOTIC AMORPHOUS SOLID KNOWN AS GLASSY WATER - COOLING WATER ULTRA FAST CONTAINING OF THE MAKES WATER BYPASSES THE RANDOM ARRANGEMENT ICE STAGE (WITH REGULAR OF MOLECULES, WHICH CRYSTALLINE LATTICE IS SIMILAR TO THAT STRUCTURE) FOUND IN G LASS. -137°C YOU WON'T FIND GLASSY WATER OUTSIDE TO FORM GLASSY WATER, THE WATER TEMPERATURE HAS TO GET DOWN TO -1370C (-215F) IN THE LAB ON EARTH, BUT IT’S THE MOST COMMON FORM OF WATER IN THE UNIVERSE - A FEW MILLISECONDS. IT'S WHAT COMETS ARE MADE FROM. AVERAGE ICE CREAM IS 25% AIR AIR IS THE KEY INGREDIENT IN ICE CREAM; UP TO A QUARTER OF THE FINISHED ARTICLE IS MADE FROM TRAPPED PARTICLES OF AIR. BEATING THE MIXTURE INCORPORATES MORE AIR BUT ALSO PREVENTS LARGE ICE CRYSTALS FROM FORMING, WHICH WOULD MAKE IT UNPLEASANTLY GRAINY AND HARD. DRY ICE IS MUCH DRY ICE COLDER THAN REGULAR ICE AND CANNOT BE HANDLED WITH BARE HANDS IT CAUSES FROSTBITE IN A VERY SHORT PERIOD ESSENTIALLY, DRY ICE IS FROZEN CARBON DIOXIDE. OF TIME. IT IS USED (C02) TO REFRIGERATE WA RM-SENSITIVE TO REFRIGE RATE FOOD TO REMOVE WARTS AND TO BAIT MOSQUITOES WHEN ELECTRICAL OTHER UNSIGHTLY AND OTHER INSECTS REFRIGERATION ISN’T MATERIALS IN BLEMISHES ON SKIN THAT HAVE SENSORS AVAILABLE.
