Liquids generally have lower

density as compared to solids.

But why some solids float on water? ​

Answer 1

Answer:

object like apple , wood and sponges are less dense than water. That because air is less than water. So that some solids float on water.

Answer 2

Liquids generally have lower density as compared to solids. But still many solids can float on water. But why ??

Detailed Explaination:

• First of all, there are two ways in which this phenomenon can be explained.

1. Compact Solids which float on water have a density lesser than that of water. The classical example is ICE FLOATING ON WATER.

• Ice has a density of 0.9 g/cc , but water has density of 1.0 g/cc.

• So, the buoyant force provided by water is equal to hold the weight of ice.

• Hence , it floats.

2. Non-compact solids are able to retain air inside themselves. This results in the average density of the solid being lesser than that of water. Classical example is SPONGE FLOATING ON WATER.

• Sponge contains a large amount of air, hence it's net density reduces and floats on water.
