The freezing point of water in degrees Celsius is 0 degrees. This standard measurement is crucial for various scientific disciplines, including chemistry and physics, where temperature is a fundamental parameter. At 0 degrees Celsius, water transitions from its liquid state to solid ice under standard atmospheric pressure. This freezing point is part of the Celsius scale, which is widely used around the world, especially in scientific contexts. It's also integral to everyday life, as it can affect weather patterns, climate, and human activities, particularly in regions that experience winter temperatures.
