Define the graph between the volume and Temperature of water​

It's one of the fundamental properties of water and it has to do with the interactions between water molecules (known as intermolecular interactions) and the way water molecules orient themselves as a result of those interactions. In water, the oxygen atom attracts electrons much more strongly than the hydrogen atoms, meaning that the electrons spend more time near the oxygen atom than the hydrogen atoms, resulting in the oxygen atom having a negative charge while the hydrogen atoms have a positive charge. This imbalance and the fact that water molecules are "bent" results in one side of the molecule having a positive charge and the other side having a negative charge and the resulting polar attractions between water molecules are among the highest of any non-ionic molecule. Beyond that, though, no one really understands the details enough to explain exactly why water's density decreases (i.e. volume increases for the same mass) when the temperature is below that minimum point. In most (but not all) other known substances, a plot of volume vs temperature would show that volume always increases as temperature increases.

hope it help u.

plz make me a brainlists.

and follow me.
