The freezing point of water is 0 degrees Celsius (32 degrees Fahrenheit) at standard atmospheric pressure. This is the temperature at which water transitions from a liquid to a solid state, forming ice. The freezing point can vary under different conditions, such as altitude or pressure, but 0 degrees Celsius is the commonly accepted benchmark. Understanding the freezing point of water is crucial in various scientific fields, including meteorology, chemistry, and environmental science, as it influences weather patterns, ecosystems, and everyday life.
