Question

On the basis of change of density with the change in temperature explain how do the the liquids get heated in a vessel​

Answer 1

Answer:

OK PLZ MARK ME IN BRAIN LIST

Explanation:

When a liquid is heated in a vessel then first of all vessel is heated and it expands slightly because expansion of solids is less than liquid,now liquid is heated and it expands more than solids. This expansion in solids and liquids is due to the increase in molecular vibration because of the heat energy which causes an increase in volume and decrease in density. If you still go on heating the liquid then due to vigorous molecular motions, separation in the molecules further increases and they are converted in to gaseous state which increases the volume and decreases the density.
