The melting point of ice is 0 degrees Celsius (32 degrees Fahrenheit) under standard atmospheric pressure. This is the temperature at which solid ice transitions to liquid water, a fundamental phase change indicative of changes in energy states. At this temperature, ice molecules gain enough energy to break the rigid hydrogen bonds that hold them together in a solid structure. The melting process continues as heat is applied, resulting in water, which is crucial for various natural processes, including weather dynamics, ecosystem balance, and thermal regulation of the environment, making it a significant temperature in both chemistry and ecology.
