Question

Why does ice floats on water?

Answer 1

HEY!!

________________________

⏩Ice is the solid state of water. Ice floats because frozen water is not denser than its liquid form.

⏩This happens because water does not follow the basic principle of thermodynamics.

⏩In other words, a solid is heavier than its liquid counterpart and should sink.

⏩However, ice has a unique molecular structure that allows it to float.

Answer 2

Answer- The above question is from the chapter 'Matter Around Us'.

Given question: Why does ice float on water?

Answer: 1. When we start cooling water, the particles come closer to each other which decreases the volume but increases the density till 4°C (volume is inversely proportion to density).

2. On further cooling, water molecules form hydrogen bonds with each other, resulting in cage-like structure with air trapped inside them.

3. Thus, volume increases, density decreases.

Hence, ice floats on water.
