Celery stalks that are immersed in fresh water for several hours become stiff. Similar stalks left in a 0.15 M salt solution become limp. From this we can deduce that the fresh water_____.     and the salt solution are both hypertonic to the cells of the celery stalks     is hypotonic and the salt solution is hypertonic to the cells of the celery stalks     is hypertonic and the salt solution is hypotonic to the cells of the celery stalks     is isotonic and the salt solution is hypertonic to the cells of the celery stalks

Physical and Chemical features

The physical property of a compound could be determined without modifying the originality of the compound. Examples of physical properties are density, hardness, color, boiling, and melting point. The chemical property expresses the ability of a compound to undergo a particular chemical change.
