answered-by-expert Expert Answer
when liquid is getting hetaed up, heat energy is absorbed by water molecules and their kinetic energy increases.
Molecules are moving with greater speed and their inter-moleculer distance increases.
This makes the volume to increase and hence density of liquid decreases with increasing temperature
