Wahts the reason behind, water expansion on cooling, below 4C?

Question

I mean mostly materials contract on cooling but water below 4C starts exapnding? Waht is the scientific reason?

Answer 1

At the low internal energy level natural polarities in the water attract eachother with greater force than those generated by internal molecular movement. This causes the the molecules to line up in precise crystaline patterns which are not jumbled as tightly as the liquid and thus expand slightly.

Answer 2

nicely it replaced into meant to be a parody of the gray Mans face that's submit whilst human beings have not created their avatar. i needed to do a variety of three-D matalic form masks of the previous 'smiley' face they used to have yet they replaced it earlier I had the possibility. I had to strengthen this one from a print out from a working laptop or laptop cafe even in spite of the incontrovertible fact that it wasn't too sparkling. I understand now I could have taken the enlarged define around to a eating place back and then re-worked the drawing from an avatar on the video show.

Answer 3

When liquid water begins to freeze, it turns into the solid form known as ice. Ice (or water in the solid form) takes up more area than liquid water does. Do an experiment with an ice tray and you can prove this theory for yourself. Good luck with your homework.

Answer 4

the temperature.
