Water is unique among most substances because it expands when it freezes, rather than contracting. This occurs due to the hydrogen bonds between water molecules, which arrange themselves in a hexagonal lattice structure as ice forms, making it less dense than liquid water. As a result, ice floats on water, which has significant ecological implications for aquatic life during cold weather. This property is essential for maintaining stable environments in bodies of water.
Adhesion is when water molecules stick to other molecules
Because they have more atoms in each molecule
No, different substances have different boiling points due to variations in their molecular structure and intermolecular forces. Water boils at 100 degrees Celsius, but substances such as ethanol, which has a smaller molecular size and weaker intermolecular forces, boils at 78.37 degrees Celsius.
Different substances freeze at different temperatures. The freezing point of a substance depends on its chemical composition and structure. Water, for example, freezes at 0 degrees Celsius (32 degrees Fahrenheit), but substances like mercury freeze at -39 degrees Celsius (-38 degrees Fahrenheit).
depends- different solents can dissolve different things: e.g, water dissolves salt, but not other things, like iron
Adhesion is when water molecules stick to other molecules
It is clean but not pure, our water contains things from other substances. When you are in different areas your drinking water can taste slightly different!
Water dissolves many substances but its molecules have both a positive and negative side. Each part of the molecule can bond with the molecules of many other substances and create a new solution. This is the reason water is considered the universal solvent.
Water can dissolve so many different substances because water has an unequel distribution of positive and negative charges(polar molecule) which attract many ions and other polar molecules.
1 tablespoon = 15 grams of water, different amounts of other substances.
Because they have more atoms in each molecule
excess water and other water soluble substances ......

Yes, water has a relatively high density compared to many other substances.
When two substances are put in the same container, they do not attract each other because different substances have different intermolecular forces. If the intermolecular forces between the two substances are weak, they are more likely to mix and not separate. This is why, for example, oil and water separate in a container due to their different polarities.
Water has covalent bonds.
15 pounds of water is 30 cups. Other substances are different .
