Why does water expand as it freezes unlike most substances so ice is less dense than water?

No because water doesn't expand when heated and when it is cooled it contracts then forms ice crystals which cause it to give the appearance that it has expanded

When water freezes it unlike other substance?
Yes. Ice is less dense than liquid water. For virtually all other substances, the solid state is more dense than the liquid state.
How do water's relative densities as a solid and a liquid differ from that od most other substances?
Ice floats. Most other substances are denser in the solid state.
What special molecular-level feature of ice explains why ice floats in water?
The crystal structure of water starts to expand after it gets down to about 4°C. This means that when the water freezes at 0°C it is less dense than it is in liquid state. Since the ice is less dense (lighter) than the surrounding water, it floats.
Why is an ice cube able to float in water?
The density of ice changes with the density of water after 0 0C
Are most materials more or less dense in their solid state than in liquid?
More dense. As a solid is formed the particles vibrate less and group closer together. One of the only exceptions to this is water. When water freezes and becomes a solid it becomes less dense which is why ice will float in your drink.

What happens to the volume of a beaker when ice melts in it?
The volume of a beaker doesn't change, it's a beaker. What your were probably trying to ask is what happens to the volume of the ice when it melts. The volume decreases; water is special. Unlike other substances when it freezes it expands. That is why ice floats, it is less dense then water.
Is a frozen pond denser than water?
Surprisingly, no. Unlike virtually all other known substances, the solid form of water is less dense than the liquid form at roughly the same temperature. That's why a full water bottle splits when it freezes, and that's why the ice floats at the top of your drink.
Why does liquid expand as it freezes?
Almost no liquids do that. Almost all become more dense when they freeze. Water is a startling exception. Water is one of the only known substances whose solid form floats in its liquid form. When water freezes, it forms crystals which occupy more space than its molecules would if they were packed together. That's because of the special shape of the water molecule, and the hydrogen bonds that it forms with other water molecules. The shape tends to form an open crystalline structure as the temperature drops below 4 degrees Celsius. By the time it freezes, it's about 9% less dense than water.
When water freezes it expands and becomes more or less dense?
It becomes less dense. Ice will float on water
How do water's relative densities as a solid and a liquid differ from that od most other substances?
Ice floats. Most other substances are denser in the solid state.
Experiment for which liquid freezes the fastest?
water because its less dense
Why does sand oil and maple surup sink in water?
more dense substances sink, less dense substances float. oil will not sink in water, it will float, it is less dense.
What are three substances from most dense to least dense?
Lead, iron and water
Is an ice cube more dense or less dense than liquid water?

What substances is less dense than air?
Plasma.
