Answer :
Intermolecular forces are the forces present between the molecules. In carbon dioxide the intermolecular force is LDM and in water, hydrogen, LDM, and dipole-dipole are present.
What is molecular structure?
Molecular structures are the arrangement of the atoms in the three-dimensional phase of the molecule along with their electrons. Water has a bent shape while carbon dioxide has linear shape geometry.
Water is a polar covalent molecule that has hydrogen and dipole-dipole bonding and forces that makes them strong enough to make them liquid at RT. On another hand carbon dioxide is a nonpolar covalent molecule that is gas at room temperature.
Sodium chloride is an ionic compound that has anions and cations in it. As it has high lattice energy it remains solid at room temperature.
Therefore, water, carbon dioxide, and sodium chloride are at different phases at room temperature.
