O.K., so we're designing a new home and I've been reading a lot; books, magazines and forums such as this hoping to find the answer to the question... what is the most cost effective system to build an energy efficient home. SIPs, double stud walls, 2x6 wall with rigid foam insulation on the exterior, spray foam, cellulose and so on. So many options, so little time.
Water interacts differently with charged and polar substances than with nonpolar substances because of the polarity of its own molecules. Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen, and a bent overall structure. The unequal charge distribution in a water molecule reflects the greater electronegativity, or electron-greediness, of oxygen relative to hydrogen: the shared electrons of the O-H bonds spend more time with the O atom than with the Hs.
Between water molecules hydrogen bonds are found which are called as intermolecular hydrogen bonding The water molecule has H-O-H, 2 hydrogen and one oxygen present. The O atom is highly electronegative in comparison to the H atom, hence it attracts the electron pair towards itself, making O atom itself partial negatively charged and H atom partial positively charged. So, water is a polar compound. The partially negative charged O atoms, (forms bond) attracts partially positively charged H atom from other molecule, forming hydrogen bond, and water forms intermolecular hydrogen bonding.
