Question

why do you think the temperature of water is shown when the value of its density is given

Answer 1

Hey friend,

Here's your answer,


The density of water is inversely proportional to it's temperature. This means that, as the temperature of the water increases, the density of water decreases.


This happens because as the temperature rises, since the particles possess kinetic energy, the molecules of the liquid move apart from each other and this rapid motion in them causes the particles to move farther away from each other.



The volume of the liquid increases on heating. Hence, it becomes necessary to measure their Temperature while measuring the density of a substance. Because mass will not change throughout, but, the volume can change on changing it's temperature.




Hope this helps!!!

Answer 2

Density increase as the temperature decreases.

This is the reason why liquid water is more dense than solid water. The bonds in water break more slowly as temperature decreases and the structure tend to trap fewer extra water molecules.
