| Well a physical change is like when you boil water and you put it over a stove, you see the water vapor? it changed the water into a gas | |
 | |  |
|
|
|
|
|
|
|
|
|
| | |
| if you take the gas and put it into a freezer, it's still water RIGHT? | |
| | |
|
|
|
|
|
|
|
|
|
| | |
| So if you were to take it out and let it melt it's still water! that is a physical change , nothing changed what the SUBSTANCE is. | |
