Question

which water is more dense, 3°C water or 5°C water
​

Answer 1

Answer:

What type of water is most dense?

Since water at about 39°F (4°C) is more dense than water at 32°F (0°C), in lakes and other water bodies the denser water sinks below less-dense water.

Answer 2

Answer:

Those two temperature are either side of the 4°C temperature where the density of water is at a maximum. So the density of water at 3°C and at 5°C will be virtually the same and just slightly less than the maximum.

Water is a polar molecule, there is a slight positive charge at the hydrogen side and a slight negative charge at the oxygen side.
