water is in the solid state , called ice & land conducts into snow & water is in the liquid state , called liquid water ->  water changes from a liquid to a solid  water changes from a liquid to a solid & freezing means matter / a substance changes from a liquid into a solid by decreasing heat energy -> the land counting the water freezes  the water freezes & hot is a mean of shows static -> water undergoes a phase change water undergoes a phase change  land undergoes a lights static & phase changes change the arrangement of molecules in a substance / in a sample -> the arrangement of molecules in water is changed by a phase change
