At atmospheric pressure no matter how small the temperature below the phase transition temperature water can exist either as liquid or solid. Right? That's what the phase diagrams show. But why do we breathe out water vapour? Is our body temperture above 100°C? Of course not! And why does water vapour exist in air around us? Also why on chilly morning we can "see" our breathes??
