Which of the following properties is not unique to water?

Surface Tension

Viscosity

Density

Adhesion

Density

Explanation:

Density is not unique only to water. All liquids have density. Liquids have density either higher or lower than that of water. All liquids have mass and they occupy the volume of the container in which they are kept. Density is the ratio of mass to volume.

Density = mass / volume.

As all liquids have mass and volume they also have density.

Density is correct one
