Hi students, in this question we need to find the true statement regarding water and ice.
00:07
Let's find out with the help of this diagram.
00:10
Water is a liquid and we can say it is the most abundant molecule in our bodies.
00:15
We have seen ice floats on water right.
00:18
Do you know why? it is because density.
00:22
Density is the measure of mass present per unit volume.
00:27
We can say lesser the density, lighter is the object.
00:31
Why does the ice has less density? it is due to the hydrogen bonds.
00:37
We know that every water molecule has two hydrogen atoms that are bonded to one oxygen atom.
00:45
Hydrogen bonds form because the positively charged hydrogen atoms get attracted to the negatively charged oxygen atoms.
00:53
However, besides being attracted to its own oxygen atom, the hydrogen atom is also attracted to oxygen atoms...
