The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. Polarity A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen. Check out video of a stream of water being bent - a plastic ruler is used in the demo. The stream of water bends due to the polarity of water ...
The polarity of water molecules means that molecules of water will stick to each other. This is called hydrogen bonding. Polarity makes water a good solvent, gives it the ability to stick to itself (cohesion), stick to other substances (adhesion), and have surface tension (due to hydrogen bonding). Check out video of a stream of water being bent - a plastic ruler is used in the demo. The ...
Here is a short list of main properties: They form crystals. Ionic compounds form crystal lattices rather than amorphous solids. They have higher enthalpies of fusion and vaporization than molecular compounds. They are hard. They are brittle. They have high melting points and also high boiling points. They conduct electricity but only when they ...
All liquids show the following characteristics: Liquids are almost incompressible. In liquids molecules are pretty close to each other. The molecules does not have lot of space between them. The molecules can not squeezed closer to one another. Liquids have fixed volume but no fixed shape.They have fixed volume but they do not have fixed or ...
What are the colligative properties? Colligative properties are physical properties of solutions that depend on the concentration of the particles and not on the kind of particles. These properties include the elevation of boiling point, the lowering of freezing point, a reduction of vapor pressure, and osmotic pressure. Consider vapor pressure.
And the six properties: 1. "Surface tension"; the surface tension of water is particularly high. 2. "Elevated specific heat capacity." 3. "Elevated specific heat of vaporization." 4. "Unusual density of liquid VERSUS solid water." That ice floats on LIQUID water is a HIGHLY unusual property for a liquid.
1 Answer. mrpauller.weebly.com. Apr 9, 2015. "Here is video showing how a paperclip can ""float"" on water - it's actually being held up by the hydrogen bonds formed between water molecules which give water its surface tension. video from: Noel Pauller. Answer link.
So things like colour, melting point, boiling point, density, hardness and so on are all physical properties. Chemical properties can only be measured and observed by making changes to the substance on an atomic/molecular scale by forming or breaking chemical bonds. So something like heat of combustion can only be measured by combusting the ...
Water has several unusual properties. 1. it expands when cooled to a solid. 2. it has an unusually large liquid range. 3. It can dissolve both ionic and covalent molecules. 1. Water is unique in that when it turns into a solid from a liquid it expands. Almost all compounds expand when turning from a solid to a liquid. This property is essential to life in that water then freezes from the top ...
Acids have Hydrogen ion concentrations of 1 (100%) to just less than 10−7. This is pH 0-6.9 Adding more acid increases the Hydrogen ion concentration lowering the pH. Bases have Hydrogen ion concentrations greater than 10^-7 to 10−14 ( 10−14 = 100% hydroxide ion concentration) This is pH 7.1-14 Adding more base increases the hydroxide ion ...
