The freezing point of water on the Celsius scale is 0 degrees Celsius. This temperature is the point at which water transitions from a liquid state to a solid state, forming ice. The Celsius scale is widely used around the world for temperature measurement, with 0 degrees marking the freezing point and 100 degrees the boiling point of water at standard atmospheric pressure. This scale is based on the properties of water, making it intuitive for everyday use. Understanding the freezing point of water is essential in various fields, including meteorology, cooking, and environmental science.
