Question

liquids generally have lower density as compared to solids. But you must have observed that ice floats on water. find out why​

Answer 1

$\huge \underline{ \underline \mathtt \pink{answer}}$

‏‏‎ ‎

Ice is formed by the freezing of water. When water freezes to form ice, then a number of empty spaces are created in solid ice (which were not present in liquid water) giving it a cage-like structure. Due to the

presence of some empty spaces, the volume of ice becomes more than an equal Maas of water, because of its greater volume, the density (maas per volume) of ice decreases. And due to it's lower density than water, ice floats on water +even though it is a solid ).

Answer 2

Liquids generally have lower density as compared to solids but ice floats on water. ...

These spaces are larger as compared to spaces in water molecules. Thus the volume of ice is greater than water. Hence the density of ice is less than of water.
