Substances have different characteristic properties, including the ability to dissolve other substances. When combined together to make a mixture, the resulting mixture has different properties depending upon the amount of each substance included. The physical properties of compounds reflect the nature of the interactions among their molecules. Water molecules are polar, which enables the negative end of one molecule to attract the positive end of a neighboring molecule, ultimately causing water's strong cohesive force. The electric force is a universal force that exists between any two charged objects.
Water is a polar molecule, resulting from the uneven distribution of charge in the molecule.
