It is true that water expands as it freezes, but the reason it floats on water is because the density of solid water (ice) is less than that of liquid water. And the density of ice is lower because of the expansion (same mass/larger volume).
Water, when it freezes into ice EXPANDS, so it floats.
Because when the water freezes it expands.
Water is unique. It expands in volume when heated, and also expands in volume when frozen (hence, burst water pipes (unless insulated) when there is a thaw after freezing winter weather).
It floats when it freezes.
No, water expands in size when frozen. That's why ice floats on water, and why pipe bursts occur when trapped water in them freezes.
Its density goes down because when water freezes it expands.
Yes, when water freezes, its molecules arrange into a crystalline structure that takes up more space than when they are in liquid form. This expansion is why ice floats in water.
When it freezes.
Water is unique because it expands when it freezes, unlike most substances that contract. This is because water molecules form a crystal lattice structure when freezing, causing them to push farther apart. This property is why ice floats on water, which is crucial for aquatic life during winter.
The crack would expand because the water in the rock, as it freezes, expands.
Water expands by about 9% when it freezes, which is why ice floats on liquid water. This expansion is due to the unique arrangement of water molecules in the solid state, forming an open crystalline structure.
When water freezes, it expands by about 15%, becoming less dense and taking up more volume. That's why ice floats.
