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 it does not alter the chemical composition of the substances involved. The molecules of the solute remain the same as when they were in solid form, just dispersed in the solvent. This process can be reversed by evaporating the solvent.

Answer 3

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 4

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

Answer 5

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

Answer 6

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