Water is a polar substance and is considered the universal solvent. It is useful in dissolving compounds that are essential to life. It also plays a vital role in most biochemical processes within the body.
physical and functional
Many chemicals contribute to the pollution of soils, waters, atmosphere.
No, water molecules maintain their polarity when frozen. As water freezes, the molecules align in a structured arrangement, but they still retain their positive and negative ends. The hydrogen bonds between water molecules also contribute to the preservation of its polarity.

-- negative polarity -- positive polarity
Yes, water's polarity allows it to form hydrogen bonds with other molecules, making it an excellent solvent for a wide range of substances. The positive and negative charges on water molecules can surround and break apart solute molecules, allowing them to dissolve in the water.
Usefully, usefulness.
the Fertile Crescent
Melting icebergs anywhere on earth contribute to elevated ocean levels. This is also true in the Southern Ocean, which surrounds Antarctica.
Reversing polarity ,changes the rotation of the device you are changing polarity on.
Its a motor that will do some work if you feed it some DC voltage. Reversing the dc supply voltage polarity will make it run in a reverse direction. The electric windows in your car is a good example of a DC motor's usefulness. The window up-down switches simply reverses the + and - polarity of the 12 volt vehicle supply to the window motor to make it take the window up or take it down.
No. Electromagnetic fields have polarity.
