What is the melting point of ice in degrees Celsius?

The melting point of ice is defined as the temperature at which ice changes from its solid state to liquid water. This transition occurs at 0 degrees Celsius under standard atmospheric pressure. At this temperature, the thermal energy of the ice molecules is sufficient to overcome the hydrogen bonds holding them in a solid structure, allowing the ice to melt into water.

Other temperatures listed, such as 32 degrees, correspond to the melting point of ice in Fahrenheit, while 100 degrees is the boiling point of water, and -32 degrees is not relevant to the melting point of ice at standard conditions. Therefore, 0 degrees Celsius is the correct answer for the melting point of ice.
