Water or H2O is a polar molecule because the Oxygen draws the Hydrogen's electrons closer to itself so the oxygen is more negative and the hydrogen's are more positive

O
H H
+ +
Water's polarity is caused by the bent geometric shape of the water molecule, and the covalent bonds between the oxygen and 2 hydrogen atoms.
Yes. Its polarity allows it to dissolve other polar substances and many ionic compounds.
No. you cant change it's polarity because electrical current that a house uses is not a + - type, it changes it's polarity 50 times per second.
Improperly wired receptacle is the normal cause.
False. Water moves up the Xylem due to a transpiration vaccuum. The polarity allows it to remain cohesive however
Reversing polarity ,changes the rotation of the device you are changing polarity on.
Yes. Its polarity allows it to dissolve other polar substances and many ionic compounds.
we do not know the cause
No. you cant change it's polarity because electrical current that a house uses is not a + - type, it changes it's polarity 50 times per second.

they live in tropical waters cause they lots of krill which eat phytoplankton
Overcharging by the alternator or if it is connected in reverse polarity.
Improperly wired receptacle is the normal cause.
False. Water moves up the Xylem due to a transpiration vaccuum. The polarity allows it to remain cohesive however
-- negative polarity -- positive polarity
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.
The case of reverse polarity would only happen on a DC system. As to would it cause equipment to run when switched off, no, if the switch opens the equipment's power supply completely the device will not operate.
