Three phases of water—solid, liquid, and gas—can coexist simultaneously at the triple point of water, which occurs at a specific temperature of 0.01°C and a pressure of 611.657 pascals. This phenomenon is a fundamental concept in thermodynamics and is crucial for understanding phase transitions. The equilibrium conditions necessary for this coexistence are precisely defined and can be referenced in scientific literature, such as the Wikipedia page on the triple point of water.
