Question

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

Answer 1

Answer:

When we heat a liquid in a beaker the liquid close to the bottom of beaker (closer to the source of heat) expands and hence its density decreases This lighter water (hot) rise up in the beaker allowing the heavy, dense cold water to take its place towards the base of the beaker causing convection current This current ultimately heats the entire liquid
