Question

(b) Density of water varies with temperature. What are its
consequences?​

Answer 1

Explanation:

The main consequence is the water has its highest density at 4 degree celsius. This means the depth of the oceans have this temperature giving the life and animals the most stable conditions to live.

Solidifies water converted into ice , if water have a the density more than ice than all the sea water from base would have become ice and all the living creature living in it will eventually die. 

Additionally warm water  causes tremendous change in the air current which transfer heat from equator to temperate zone. Hence, play role in controlling climate of whole earth.

Answer 2

Answer:

(b) Density of water varies with temperature.

(b) Density of water varies with temperature and its consequences are:

When cooled from room temperature liquid water becomes dense but at 4 degree Celsius pure water reaches its maximum density. As it is cooled it expands to become less dense. The solid ice is denser than the liquid phase so it sinks in the
