Question

Define density and why ice floats on water​

Answer 1

The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. The symbol most often used for density is ρ, although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: where ρ is the density, m is the mass, and V is the volume. 


As it cools further and freezes into ice, it actually becomes less dense. On the other hand, most substances are most dense in their solid (frozen) state than in their liquid state. Water is different because of hydrogen bonding. ... The heavier water displaces the lighter ice, so ice floats to the top.


I have answer with photo to understand better if it is perfect then Mark's as brainlist

Answer 2

Here is your answer mate ...

Q1. Define Density?

Ans.) The relation of the weight of a substance to its size is called Density.

Ex.-- Lead had a high density.

Q2. Why ice floats on water ?

Ans.) As it cools further and freezs into ice , it actually becomes less dense . On the other hand , most substance are most dense in their solids (frozen) state than in their liquid state , water is different because of hydrogen bonding .... The heavier water diaplaces the lighter ice , so ice floats on the top .
