The most simplified meaning within a language is MORPHEME.
In English language, a morpheme refers to a language unit, that is made up of a word or a word elements which can not be further broken down into meaningful smaller parts. Morphemes are the smallest, basic, grammatical unit of a language that have distinct meaning, just as atoms are the smallest unit of elements in chemistry. Examples of morphemes are: sad, joy, depress, excited, etc.

The formula is B2O3. The charges need to equal each other to obtain a neutral compound of no charge hence 2 B has a charge of +6 and 3 O has a charge of -6 to cancel out each other, resulting in a stable uncharged compound.
The attraction of inter-molecular forces between molecules is defined by a general term "Van der Waals forces". It is the weak interactions caused by momentary changes in electron density in a molecule.
Inter-molecular forces that are present between hydrogen atom which is bonded to highly electronegative atom (
) and the lone pair electrons present in the other molecule on these electronegative atoms is known as hydrogen bonding.
The type of interactions between methane,
is Van der Waals interactions whereas in water,
is hydrogen bonding.
Since, the hydrogen bond is stronger than the Van der Waals forces so, it results in higher strength between the molecule possessing hydrogen bonding. Thus, molecules possessing hydrogen bonds will have higher boiling point than the molecules which possess Van der Waals forces.
Hence, water (
) have a significantly higher boiling point than methane (
) because water molecules are attracted to one another by hydrogen bonds.
