Exceptional State, In Case Of Between Water And Ice

Chemistry Level 2

Why doesn't the i c e ice float on the W a t e r Water surface?

Because ice melt Because ice has low density than water Becuase ice is lighter than water Because ice has empty spaces between molecules

Ice floats on the water surface because of only empty spaces between molecules.There doesnt matter the how it is huge enough. as comparatively we see Ice structure is different rather than water molecule.ice has hexagonal structure where as water molecule has tetrahedral structure.One of them hexagonal structure get more space to interact and stability it make empty spaces between molecules ,but in case of water its structure comparatively too closed to each other and in their no any empty space so water gets havier than Ice...and Ice density is do not matter here its same for ice and water in 1000 cm³ or 1dm³.

The main point is density not empty spaces, see buoyant force (why an object floats).

Actually you are absolutely right for density but not for kind of buoyant force. There are main two reason for an object to float it would be either force or density. here i didnt thinking about force but about density of object. The density is the product of mass and volume. density is nothing but the space that occupies by the molecules .

and density isnt empty but the molecules occupies induvidule space per cube is two low ice but in liquid its high.I may refer the book about density causes much to shows various property.

The force or density are one and the same reason for an object to float, if it has less density then it will encounter more buoyant force than its own weight, so the object will float. (Fluids(gas or liquid) have the property of buoyant force).

Density is mass/volume greater the volume lesser the density both the answers are correct here as they both lead us to same "density of ice is less then water" BECAUSE "ice has empty spaces between molecules" resulting in greater volume or lesser density.

But the answer says that ice melts & that's why it doesn't float over water surface.

what, if consider that ice wont melt or by maintaining constant temperature.
