Intermolecular forces between molecules significantly affect their physical properties. Water (H2O) exhibits three distinct forms—ice, liquid water, and steam—each with unique physical characteristics. The document emphasizes that despite being the same substance, H2O shows considerable differences in properties across its states.

1. Intermolecular forces exist between molecules and influence the physical
properties. We can think of H2O in its three forms, ice, water and steam. ... However, the
physical properties of H2O are very different in the three states.
