Water is a covalent molecule (one where the electrons are shared between the atoms). If you ever tried to share something with someone, then you know that it is difficult to share equally. The same is true for atoms. Some atoms like to hog electrons more than others (measured by what is called electronegativity), so they will pull the electrons towards themselves and away from the other atoms.
In water, oxygen is the electron hog (has a higher electonegativity) and the hydrogen is left wanting. The electrons spend more time with the oxygen atom, so it gains a slight negative charge. In contrast, the hydrogen atoms has a slight positive charge. These slight charges and the shape of water (bent - like the letter "v") make the water molecule polar (having two poles - positive and negative).
Most people know that opposites attract, so that is what happens here. The negative oxygen is attracted to the positive hydrogen atoms of other water molecules. This attraction is what causes a hydrogen bond to form. A hydrogen bond is not as strong as a covalent bond, but it is still very strong.
This hydrogen bonding in water is responsible for many of its unique properties like high surface tension (pain when you do a belly flop), evaporative cooling (why sweating cools you off), and many other unique properties. hi mr Morris and ms urez there my science teachers
What is meant by polarity? Answer An electric charge has a polarity of either positive or negative. Also a voltage has a polarity, in that it could be positive or negative, with respect to some other voltage, such as the one at the other end of a battery or electric circuit.
Direct Current Electrode Negative (DCEN) - The direction of current flow through a welding circuit when the electrode lead is connected to the negative terminal and the work lead is connected to the positive terminal of a DC welding machine. Also called direct current, straight polarity (DCSP).
Direct Current Electrode Positive (DCEP) - The direction of current flow through a welding circuit when the electrode lead is connected to a positive terminal and the work lead is connected to a negative terminal to a DC welding machine. Also called direct current, reverse polarity (DCRP).
Either positive or negative (a relative shortage OR excess of electrons).
Chucky
The polarity is a vector quantity. The resultant of the polarity of bonds determines the polarity of the molecule. In CO2 there is polarity between the two C-O but the polarity is equal and opposite in direction so CO2 doesn't have polarity. If the polarity of bonds is not cancelled then the polarity remains in the molecule.
Polarity
Explain the effect of molecular polarity on behaviour.
A sulfur molecule has zero polarity.
because there is polarity of molecules in there
polarity means how much quantity soluble in water
what do ya mean by "Polarity" for the following parameters? Charge: Voltage: Current: Meter Probes:
Check your spelling - is the word you are requesting: polarity?
Polarity is the direction of flow of electrons throughout a circuit. There are two types of polarity: positive and negative. Postive polarity is of older circuits which means electrons flow from positive to negative. Negative polarity is of more modern circuits and that is the flow of electrons from negative to positive such as on car batteries
If, by 'reverse polarity', you mean the accidental reversal of the line and neutral conductors at the socket outlet or receptacle, then the answer is no.
i dont know dont care

-- negative polarity -- positive polarity

Polarity
It means to be happy or sad or angry or calm
Reversing polarity ,changes the rotation of the device you are changing polarity on.
