Why Ice Does not Sink on The Water
Ice doesn't sink because, unlike almost every other solid substance, its solid form (ice) is less dense than its liquid form (water) . Here is a breakdown of why this occurs: 1. The Role of Density Floating Rule: An object floats in a fluid if its density is less than the density of the fluid it displaces. Water's Numbers: The density of liquid water is highest at about 4^{\circ}\text{C} (approximately 1.00 \text{ g}/\text{cm}^3). The density of ice at 0^{\circ}\text{C} is approximately 0.917 \text{ g}/\text{cm}^3. . Conclusion: Since ice is about 9% less dense than liquid water, it floats. 2. The Unique Structure of Water Molecules The reason for this density difference is the way water molecules (\text{H}_2\text{O}) arrange themselves due to hydrogen bonding . Liquid Water (above 4^{\circ}\text{C} ): Water molecules are constantly moving and sliding past each other. They form and break hydrogen bonds frequently,...
