hey!
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.
Try this,
Place hot and cold colored water into room-temperature water. You'll observe that the hot water floats on the room-temperature water and the cold water sinks. This concludes that hot water is less dense than room-temperature water and that cold is more dense at room temperature.
hope it helps uh!
