When ice melts what happens to the water molecules

when ice melts, hydrogen bonds between molecules breaks and water molecules get closer to each others.

Explanation:

When water is cooled below 0°C, ice is formed. In ice form water molecules have more hydrogen bonds. When temperature increases, hydrogen bonds between water molecules breaks and water gets melt. If the temperature is continue to increases the water molecules acquire more kinetic energy and get escape from the surface converted into gas molecules. In liquid form water molecules are get closer to each other as compared to the ice form. This is the unusual behavior of water as compared to the other substances in solid form.

In ice form water molecules are strongly bonded but the distance between the water molecules are more or we can say that their are empty spaces present between water molecules that's why ice is less dense than the liquid water.
