What are three unusual properties of water?

Answer 1

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

Answer 2

Most things (solid and liquid) will expand when heated and contract when cooled. Water liquid expands when heated and cold water (below 4oC) expands when cooled, even more when it's iced (solid).

Answer 3

The properties of water include capillary action, surface tension, the ability to dissolve many substances, and the high specific heat.

Less obviously it contracts as it cools until it reaches 4oC when it starts to expand, it is easily disassociated into its components (H2 and O2)with the application of electric current, it can exist as a solid liquid and gas at a reasonable (room) temperature.

Answer 4

Following are some of the unique properties of water:

• In the solid state, the particles of matter are usually much closer together than they are in the liquid state. So if you put a solid into its corresponding liquid, it sinks. But this is not true of water. Its solid state is less dense than its liquid state, so it floats.

• Water's boiling point is unusually high. Other compounds similar in weight to water have a muchlower boiling point.

• Another unique property of water is its ability to dissolve a large variety of chemical substances. It dissolves salts and other ionic compounds, as well as polar covalent compounds such as alcohols and organic acids.

Answer 5

1. Water reaches its highest density at 4 degrees Celsius, causing ice to float in liquid water.
2. Water has a high surface tension due to hydrogen bonding, allowing insects to walk on its surface.
3. Water exhibits anomalous expansion when cooled below 4 degrees Celsius, causing it to expand instead of contract.

Answer 6

It is liquid at room temperature with a molecular weight of only 18 and ice is less dense than liquid water.

Answer 7

it expands when freezing instead of contracting in the solid state like most substances do..
