how does the density of liquid water compare with the density of ice

Question

odys · Answer

what do you mean by density

odys · Answer

molecules or something else

anonymous · Answer

Yes like liquid water && ice

odys · Answer

well as well as i know water has less density than ice

anonymous · Answer

water's density is 1.0 && ice's density is 0.9

odys · Answer

oh wait yeah sorry learned about it a while ago i'm sorry

anonymous · Answer

umm its fine.. i still need help thoe

odys · Answer

Well water can take any shape and ice can't

odys · Answer

like ice can fit in anything ice can't

odys · Answer

i mean water

density is a measure of how much mass you can fit in a given volume, mathematically, it's $\rho=\dfrac{m}{V}$. Consider these 2 solids. |dw:1416448014216:dw|

If 1 and 2 are the same volume, 1is more dense because it has more mass.

in terms of water, when liquid there is less space between the molecules because there is more kinetic energy, the molecules are constantly smashing into one another. When solid (ice), water molecules arrange themselves into a tetrahedral network through hydrogen bonding. This means it has a fixed shape and more space between individual molecules than in water.
