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.
The total charge on a water molecule is neutral, the charge is unevenly distributed across the water molecule. Because of this uneven distribution of charge, water is called a __________ compound. Polar. A __________ is the force of attraction between a hydrogen molecule with a partial positive charge and another atom or molecule with a partial or full negative charge.
