Question and answer
how is physical and chemical changes alike
Chemical changes the physical composition while physical just changes form of substance. Example... you demonstrate a physical change by freezing water... it is still water, but it is frozen, so the atoms are moving slower and are less agitated. [ You add salt to the water, you now have salt water which is something like Na+Cl+H^2+O versus the standard H^2+O This substance is physically
harder to freeze and requires colder temperatures... ]
