Question

How does density of a liquid vary with temperature? please answer its very urgent

Answer 1

Hi!!! here is your answer....

Density is the ratio of mass to volume. When the temperature varies, the volume of the liquid changes.

Eg. Liquids expand on heating.

So due to this change is volume, the density varies with change in temperature.

In simpler words, heating a substance causes molecules to speed up and spread slightly further apart, occupying a larger volume that results in a decrease in density. Also, cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density.
