Water's polarity helps make it an excellent solvent. Polar substances dissolve well in water as "like dissolves like," but nonpolar substances do not dissolve as readily. Hydrogen bonding gives water its cohesion and surface tension, allowing it to cling to itself. It also greatly affects water's freezing behavior and density. Hydrogen bonds are responsible for the characteristic crystal lattice structure of ice.
Examples: boiling and freezing point, specific heat, polarity of the molecule, density, surface tension, solvent ability, etc.
High heat capacity, Polarity/ Solvent properties, Chemical reactivity and Cushioning in the body.
A physical property refers to a measurable value that describes a state of a physical system. Some examples of physical properties of matter are color, odor, density, solubility and polarity.
Matter can be insoluble in alcohol in soap and detergents because alcohol is hydrophilic (water-loving), while some components in soap and detergents are hydrophobic (water-repelling). This difference in polarity between the alcohol and the matter prevents them from mixing and dissolving in each other.
Some examples of chemical properties for water include its ability to react with certain metals to produce hydrogen gas, its ability to act as a solvent for many substances due to its polarity, and its participation in acid-base reactions where it can act as both an acid and a base.
It is not a conductor.
Water has extremely high polarity, making it an effective solvent for ionic and polar materials. It is non toxic and easy to dispose of. It does not have toxic fumes. It is cheap to obtain ( in some forms and compared to other solvents ).
There are various ways. Some elements can be determined by taste, color, optical properties, reaction to mass spectrometry, reaction to chemicals etc. It depends on the element.
Some of the physical properties of sodium chloride can be determined by simple observation: it is a cubic crystal, it dissolves in water, and it tastes salty (but do not taste chemical unless told to do so by your instructor!). Other properties require lab equipment: it's melting point, it's solubility constant, it's density, etc.
Some capacitors are polarity sensitive; some are not. It depends on the design. Electrolytic capacitors, for instance, are polarity sensitive, while ceramic disc capacitors are not. You can generally tell, if the capacitor is marked with polarity signs, such as + and -, if it is or not.
