Even a new, minimum efficiency air conditioner or furnace can be a significant jump in efficiency. The old furnace in your basement may only be originally rated at 60% to 70% AFUE. In order to comply with national regulations, furnaces manufactured today have to be rated at a minimum of 80% AFUE.
dipole - a pair of equal and opposite electric charges or magnetic poles separated by a small distance. couple - (physics) something joined by two equal and opposite forces that act along parallel lines. electric dipole, electric doublet - a dipole with equal and opposite electric charges.
To have a dipole moment, we need to have atoms with DIFFERENT ELECTRONEGATIVITY. This is simple to explain: the atom that is more electronegative in the bond will pull, not only its own electrons tighter, but will also pull the electrons of the neighbor atom.eport Abuse. A dipole is a separation of positive and negative charge. In chemistry, it is used to refer to the distribution of positive and negative charge across a molecule. A dipole moment has a direction in space, therefore it is a vector.
