What types of compounds can exist as liquids gasses and solids?

Compounds that can exist as liquids, gases, and solids typically include those with varying molecular forces and structures, such as water (H₂O), carbon dioxide (CO₂), and ammonia (NH₃). These compounds can transition between states depending on temperature and pressure conditions. For instance, water can be ice (solid), liquid water, or steam (gas) depending on the environment. Generally, substances with low molecular weights and weak intermolecular forces tend to have a larger range of phase states.
