Dissolving in water is a physical change.
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.
this is a chemical change because you can't reyurn it back to salt
It is a physical change because the chemical composition of the salt and water does not change.
The dissolving of salt in water is a physical change because it does not result in a chemical reaction. The salt molecules are simply breaking apart and becoming dispersed in the water, but there is no change in the chemical composition of the salt.
Chemical
Yes, salt dissolving in water is a physical change because it does not involve a change in the chemical composition of the salt. The salt molecules are simply dispersed in the water, but they remain the same chemical substance.
Salt is a material not a change.
The melting point is a physical property of materials.
Physical
A match burning is a chemical change. Salt dissolving in water is a physical change.
It is chemical. It is chemical because when salt is formed from elements it becomes a chemical and not a physical.
Solubilization of salt in water is a physical change.
