**Melting Point of Distilled Water**

**Introduction:**
The melting point of a substance is the temperature at which it changes from a solid state to a liquid state. Distilled water, also known as pure water, is composed of hydrogen and oxygen atoms in the form of H2O molecules. As water freezes, the molecules arrange themselves into a regular pattern, forming a crystalline structure. Let's explore the melting point of distilled water in detail.

**Factors Affecting Melting Point:**
Several factors can influence the melting point of a substance, including:
1. Purity: Impurities can lower the melting point of a substance. Since distilled water is highly pure, it is expected to have a higher melting point compared to water with impurities.
2. Atmospheric Pressure: The melting point can also be affected by atmospheric pressure. However, at normal atmospheric pressure, the impact on the melting point of water is minimal.

**Melting Point of Distilled Water:**
The melting point of distilled water is 0 degrees Celsius or 32 degrees Fahrenheit under normal atmospheric pressure. This is the temperature at which solid ice transforms into liquid water. It is important to note that this is the standard melting point of water at sea level. At higher altitudes, where atmospheric pressure is lower, the melting point can be slightly lower.

**Explanation:**
When the temperature of water decreases, the kinetic energy of the water molecules decreases as well. As a result, the attractive forces between the water molecules become stronger. At the melting point, the energy supplied to the water molecules is sufficient to break the intermolecular forces holding the water molecules in a fixed arrangement, allowing them to move freely and transition from a solid to a liquid state.

The melting point of water is specifically 0 degrees Celsius due to the unique properties of hydrogen bonding between water molecules. Hydrogen bonding is a strong intermolecular force that holds the water molecules together in a solid state. As the temperature rises above 0 degrees Celsius, the hydrogen bonds weaken, allowing the water molecules to move more freely and transition into a liquid state.

**Conclusion:**
In conclusion, the melting point of distilled water is 0 degrees Celsius or 32 degrees Fahrenheit under normal atmospheric pressure. This is the temperature at which solid ice transitions into liquid water. Understanding the melting point of water is essential in various applications, such as determining the freezing point of substances, studying phase changes, and understanding the behavior of water in different environmental conditions.

As we know the melting point of liquid at room temperature is 0 degree centigrade....
