Question

Chemistry sheet class 9 why does ice float on water

Answer 1

Answer:

it has lower density than watee by 9 percent and has many air spaces in it

Answer 2

Explanation:

According to Archimedes’ principle -For an object to move on water, it must displace an equal amount of water. For this, we need to find the fluid's weight that is displaced by the object.  

Most of the substances are denser when in their solid (Frozen) states. But in case of water, when it 'freezes into ice', it becomes less dense because of 'Hydrogen bonding'. The water that is heavy displaces the ice that is light in weight, so the ice floats on the top of the water.
