Answer:

Density is defined as the mass of a substance divided by the volume of the substance.

Mathematically,    Density =

In cold water, molecules are more closer to each other due to which there occurs increase in mass of the substance. As density is proportional to mass of the substance. So, density of cold water will be more.

On the other hand, in warm water molecules have more kinetic energy so, there will be more number of collisions. As a result, molecules will move away from each other due to which there will be decrease in density.

Thus, we can conclude that the statement cold water is more dense than warm water, is true about the density of cold water.
