Answer:
1) Water molecules are polar.
The two molecules of hydrogen are slightly positively charged, whereas the molecule of oxygen is slightly negatively charged. This is because the electrons are more attracted to the oxygen end of the molecule than the hydrogen end.
2) Water molecules frequently organize into spheres.
This is due to the molecules' mutual attraction to one another due to gravity. They also increase surface tension, which also promotes the formation of water spheres. The hydrogen bonds that exist between molecules are what produce the surface tension. This has a balance between being weak enough to be readily disturbed and robust enough to support its own weight inside the sphere.
Hope this helps! :)
