Answer 2

Physical properties are anything that will change how it looks but not how it acts.

for example one could be a phase change. where water turns into steam. which is just water in gas form


another example would be pebbles are just rocks but crushed up.

and another physical change would dents. like if you hit a table and it got a dent. it's still a table just with a dent.


chemical changes change the actual way the chemical works.



the way you can tell is by if it gets heat or has a new property that wants their before.

some examples would be lighting wood on fire. it changes the composition of the wood and now it is no longer flammable.

another one would be burning magnesium. it becomes a new substance when you burn it.

the last example could be photsynthiss. you start with carbon and water and turn it into glucose and oxygen
