These seven properties are water forms hydrogen bonds, which cause cohesion, adhesion, high specific heat, high heat of vaporization, it is a universal solvent, and water is less dense as a solid. Water forms Hydrogen Bonds - Since Oxygen is far more electronegative than hydrogen, it withdraws electron density from hydrogen giving the hydrogen a partial positive charge and the oxygen a partial negative charge. These partial opposite charges attract to each other on other water molecules, allowing water molecules to hydrogen bond to each other. This accounts for all the following properties. Cohesion - Water can stick to itself Adhesion - Water can stick to other materials High Specific Heat - Water changes its temperature slower than most other compounds High Heat of Vaporization - Water requires a large amount of energy to change it into a gas Versatile Solvent - Water can dissolve a wide variety of things
Water is less dense as a solid - Most substances gain density when frozen
Hydrogen bonding between water molecules is responsible for many of water's unusual physical properties, such as high surface tension, cohesion, and adhesion. This bonding is a result of the attraction between the partially positive hydrogen atoms of one water molecule and the partially negative oxygen atom of another water molecule.
Three mediums through which a wave can travel are air, water, and solids like metals. Waves propagate differently depending on the medium's properties, such as its density and elasticity. In each medium, the speed of the wave will vary due to these properties.
Physical properties of pond water include temperature, color, turbidity (clarity), odor, taste, and specific gravity. These properties can indicate the overall health of the water and its suitability for supporting aquatic life. Monitoring these physical properties is important for assessing water quality and potential pollution.
Materials that are effective water insulators typically have properties such as low porosity, high density, and a lack of water-absorbing capabilities. These properties prevent water from easily passing through the material, making it an effective barrier against water penetration.
Density, melting point, and boiling point are three examples of intensive physical properties. These properties do not depend on the amount of substance present and are useful for identifying and characterizing materials.
when water freezes, it expands. Most elements contract when frozen.
These elements are: - radioactive - dangerous - rare - expensive
After my opinion nitrogen hasn't any unusual and very specific properties.
metal

Water in three of its forms is solid which is ice, liquid which is just water, and gas which is water vapor.
Water is considered an unusual molecule because of its unique properties, such as high surface tension, high specific heat capacity, and solid form (ice) being less dense than its liquid form. These properties are due to hydrogen bonding between water molecules, which gives water its special characteristics and behavior unlike other liquids.
Universal solvent, polarity, density, cohesion, adhesion
Mostly from the fact that there is strong hydrogen bonding between the molecules. This, for instance, gives water much higher melting and boiling points than we'd otherwise expect for such small molecules.
It is chemically inert gas
Examples: density, reactivity, phase.
