I suspect the answer wanted is density. the density of ice is less than that of water. Think of icebergs - they float- this all down to those hydrogen bonds keeping the water molecules further apart in the solid than they are (on average) in the liquid. Another answer could be the density maximum of water is approx 4 0C which is great for fishes as the water "shrinks away" from the ice on the surface as it cools. This is again due to H bonds which as the water starts to form larger and larger molecular structures held together by H bonds, (these are dynamic structures-but tend to get larger and less dynamic as temperature decreases.)- water molecules come and go all the time .
What else can I help you with?
What kind of bonds do alcohols form between individual molecules?
Alcohols can form hydrogen bonds between individual molecules. These hydrogen bonds are attractions between the partially positive hydrogen atom of one molecule and the partially negative oxygen atom of another molecule. This plays a significant role in the physical and chemical properties of alcohols.
What is the order of hydrogen bond strength in various molecules and how does it impact their properties?
Hydrogen bonds are strongest in water, followed by ammonia, and then in alcohols. The strength of hydrogen bonds affects properties such as boiling point, solubility, and viscosity in these molecules.
How does hydrogen affect the properties of water?
Hydrogen in water molecules forms hydrogen bonds, which give water its unique properties such as high surface tension, cohesion, and adhesion. These properties are important for various biological and chemical processes.
Why does hydrogen molecule does not exist?
Hydrogen molecules do exist but they are less stable than hydrogen atoms. This is because hydrogen molecules require a large amount of energy to form since hydrogen atoms are highly reactive and tend to exist independently. Additionally, hydrogen molecules can easily dissociate into individual atoms at lower temperatures.
How does the presence of hydrogen bonding affect the properties of molecules in a chemical compound?
Hydrogen bonding affects the properties of molecules in a chemical compound by increasing the boiling point, melting point, and solubility of the compound. This is because hydrogen bonding creates strong intermolecular forces between molecules, leading to greater cohesion and stability within the compound.

Pure substances that have properties entirely different from the atoms that make it up are?
compounds. Compounds are formed when atoms of different elements chemically bond together to create a new substance with unique properties that are different from the properties of the individual atoms. An example of a compound is water (H2O), which has different physical and chemical properties compared to its constituent elements, hydrogen and oxygen.
Why do water and hydrogen peroxide have the same chemical and physical properties?
They both are made of hydrogen and oxygen. Has 2 H bonds among molecules. They have a few different properties too.
How does the composition of a mixture of hydrogen and oxygen differ from the composition containing hydrogen and oxygen?
A mixture of hydrogen and oxygen would consist of separate H2 and O2 molecules. The hydrogen and oxygen would retain their own properties. The most common compound of hydrogen and oxygen is water. In it the two elements are combined into molecules of H2O, which has its own set of properties distinct from those of hydrogen or oxygen.
What is the cohesive properties of the water?
This property due to the formation of hydrogen bonds between water molecules is the cause of the water molecules sticking.
How the interactions of water at the molecular level enable it to possess different properties?
These properties are due to the association of water molecules by hydrogen bonds.
How does a mixture of hydrogen and oxygen differ from a compound of hydrogen and oxygen?
A mixture of hydrogen and oxygen means that the two gasses would be mixed together, but remain chemically distinct from one another and retain their own properties. You would still have separate hydrogen and oxygen molecules. In a compound of hydrogen and oxygen, water, the two elements are chemically combined to form a new substance with its own set of properties.
Why do hydrogen and oxygen have different properties than hydrogen peroxide?
Hydrogen peroxide is a compound made of hydrogen and oxygen atoms bonded in a specific way, giving it different chemical and physical properties than the individual elements. The presence of an extra oxygen atom in hydrogen peroxide results in different intermolecular forces and reactivity compared to pure hydrogen or oxygen molecules.
