Final answer:

The order of increasing melting point for NaCl, CO2, and H2O is CO2, H2O, NaCl.

Step-by-step explanation:

The order of increasing melting point for the substances NaCl (sodium chloride), CO2 (carbon dioxide), and H2O (water) is as follows:

  1. CO2 (carbon dioxide)
  2. H2O (water)
  3. NaCl (sodium chloride)

Carbon dioxide has the lowest melting point, followed by water, and then sodium chloride. This is because carbon dioxide is a nonpolar molecule and has weak intermolecular forces, water is a polar molecule with stronger intermolecular forces, and sodium chloride is an ionic compound with strong ionic bonds.
