Question

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

Answer 1

Answer:

• when water is cooled , its density increases
• But when temperature of water reaches 4 degree celsius , water will have its maximum density
• So then after if water is further cooled from 4 degree celsius , its density decreases . This is an anomalous property of water ( that is , water only show this property )
• So at 0 degree celsius ( that is when  water turn ice ) the density will be less than the density of water
• Since ice has density less than water , it floats in it

hope the answer help u

$\large\green{\underline{\underline{\mathscr{\red{\:\:\:\:\:Answer\:\:\:\:\:}}}}}$

Density of ice is less than the density of water.The low density of ice can be attributed to the small pores it was which allows it to trap air.Hence ice floats on water.
