Question

Give reason ( Why density of almost all the solids,liquids and gases decrease with increase in temperature)

Answer 1

Hii There!!!

Since, when temprature is increased the molecules of solid, liquid and gases starts moving rapidly.

Thus, it increases the volume and decreases the density.

Mathematically, Density = Mass / Volume
