The melting point of pure water is 0 degrees Celsius (32 degrees Fahrenheit) at standard atmospheric pressure. This temperature is the point at which water transitions from its solid state (ice) to its liquid state (water).
When heat is applied to ice, the temperature begins to rise until it reaches the melting point. At this point, the added energy causes the molecular structure of ice to break down, allowing the ice to change into liquid water. This process involves the absorption of heat without a change in temperature until all the ice has melted.
It’s important to note that various factors can influence the melting point of water, including pressure. For instance, at higher altitudes where atmospheric pressure is lower, the melting point of ice can decrease slightly.
