The melting point of ice in Celsius is 0 degrees. This is the temperature at which solid water (ice) transitions into liquid water under standard atmospheric conditions. The concept of melting and freezing points is fundamentally critical in the study of thermodynamics and physical sciences. The relationship between temperature and the state of water is significant in various natural processes and ecosystems. Understanding this temperature point assists in predicting weather patterns, examining climate change effects, and even in culinary applications. It's also essential in various scientific experiments and applications, emphasizing its relevance across multiple disciplines.
