Physical. Chemical change is when the composition of a molecule is changed. Example: When you burn wood. The wood stops being wood and turns to ash. An example of a Physical change is when you mix salt in water. Neither the salt nor the water change their chemical makeup. If you allow the water to evaporate the salt remains and still has the same chemical make up, as does the water even though it is now in its gaseous form.
Mixing salt and water is a physical change, not a chemical change. The salt does not change its chemical composition when it dissolves in water, only its physical state.
Physical change as no new substance is formed and the properties have also not changed. Hope it helps!

This is a physical change. You can separate the salt and water by the physical process of distillation or evaporation where the water is boiled away and the salt is left behind.
For example melting and boiling of salt are physical processes.

this is a chemical change because you can't reyurn it back to salt
Physical
It is a physical change because the chemical composition of the salt and water does not change.
Solubilization of salt in water is a physical change.
