What are Aliphatic molecules?

They are basically noncyclic or cyclic molecules that are not aromatic. Thus, instead of the normal benzene ring that has 3 double bonds inside, it is just a saturated closed ring.

A molecule is more than one atom that move and act as an electrically neutral unit, held together by electrostatic forces between atoms called covalent bonds. A molecule has: -nuclei - that comprise...

Yes, water is a bend molecule with a bond angle of about 105 degrees. They are described as bent planar (or V shaped)

if you mean the transfer rate of heat ?; the heat transfer rate depends on the atom or molecule type .

Air molecules is a little vague, the air that we breath is a mixture of mainly nitrogen (72% or so) oxygen and carbon dioxide. A water molecule is H20, two hydrogen polar covalently bonded to one...
