CARBON DIOXIDE CAR EXHAUST RAIN MILK TEA HELIUM ICE JUICE BLOCKS ALCOHOL OIL BOTTLE WOOD GASOLINE STEAM Phase Changes of Matter → change of a solid into a liquid process whereby atoms or molecules in a liquid state gain sufficient energy to enter the gaseous state solid transform into a gas phase without first melting to form a liquid phase Process by which gas phase changed into liquid phase Liquid turn into solid gas transforms into solid without passing through the liquid phase 1. __________________ 2. __________________ 3. __________________ 4. __________________ 5. __________________ 6. __________________
