What else can I help you with?
Most substances become less dense as the temperature increases. Which substance is an exception to this rule?
Water is an exception to this rule as it becomes less dense when it freezes and forms ice. This is due to the unique arrangement of water molecules in ice compared to liquid water, causing it to expand and become less dense.
Is ice more or less dense than than liquid water?
Ice is less dense than water at the same pressure. That is why ice cubes and icebergs float on the water.
Does Ice floats in water because water molecules in ice are more tightly packed than in liquid water?
Ice floats because it is less dense than water. When water freezes, it creates a crystal lattice that occupies more volume than the water did. Because it is less dense, ice is displaced by water (and floats on top). If enough ice is forced below the surface by its weight, you can have ice on top and ice below (as in an iceberg).
When water is frozen is it heavier?
When water freezes, it expands and becomes less dense, causing it to float. This is due to the unique hydrogen bonding structure of water molecules. Therefore, ice is actually less dense than liquid water, making it lighter.
Does polar water diluted by melting ice become less or less dense?
less denser than

Experiment for which liquid freezes the fastest?
water because its less dense
Icecubes float in water because they are less?
Dense
Is ice denser than cold water?
no, when water freezes it becomes less dense, that is why ice floats.
Why is ice less dense than water?
Ice is less dense than water because when water freezes and turns into ice, the molecules arrange themselves in a way that creates empty spaces between them, making ice less compact and therefore less dense than liquid water.
What type of bonds cause water to expand when it freezes?
Hydrogen bonds cause water to expand when it freezes. As water cools and freezes, the hydrogen bonds between water molecules form a crystalline structure with a more open arrangement than in its liquid state, causing it to expand and become less dense.
A piece of ice floats on water. what does this tell you about the density of ice compared to the density of water?
It tells you that the ice is less dense than the water.
Is liquid water less dense then Ice?
No. Ice is less dense than water. Because ice is less dense it displaces less water and floats. Water is most dense at 4o C. any change in temperature, either up or down, lowers the density.
How dose freezing cause water to become denser?
When water freezes, its molecules lose energy and get stuck in a lattice structure in which they are farther apart from each other than in their liquid state, thus making ice less dense than water
Does polar water diluted by meltings ice become more or less dense?
less denser than
When water freezes it expands and becomes more or less dense?
When water freezes, its molecules form a crystalline structure that causes them to space out more than in liquid form, leading to expansion. This expansion lowers the density of ice compared to liquid water, which is why ice floats.
What is it called when a solid is less dense than its liquid?
This is called anomalous expansion or the anomaly of water. It means that when water freezes, its solid form (ice) is less dense than its liquid form, which is why ice cubes float in water.
