Question

how does the density of a liquid or gas vary with temperature ​

Answer 1

$\huge\red{answer}$

When the temperature varies, the volume of the liquid changes. ... 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
