Explain why dissolving is a physical change?

Answer 1

All physical changes are reversible because the molecules do not undergo change in any chemical reaction even in in the change in the state of matter. NaCl is a salt compound and each molecules gets easily dissolved in water and the salt recovered by evaporation of water.

Answer 2

Dissolving is a physical change because the physical property changes but a new chemical substance does not form. An example is dissolving salt in water.

Answer 3

Because it is not a chemical change, and the molecular properties of the substance are not changed

Answer 4

Dissolving salt is a physical change because the salt changes from a solid form and melts into the liquid it is dissolved in.

Answer 5

Dissolving is a physical change because there is no change in chemical makeup of the solute or the solvent. There is no chemical reaction.
