Answer:
D) adhesion
Step-by-step explanation:
Adhesion is a water property that allows water molecules to adhere to each other. This can occur thanks to its polarity. Water tends to attract and be attracted to other polar molecules. This attraction between water molecules and other polar molecules is called adhesion. When the slope occurs the water surface becomes curved, as shown in the figure.
Water molecules do not bind with nonpolar molecules, ie there is no adhesion. Therefore it is not evenly distributed on a waxed surface, and forms separate droplets on them, as the wax is nonpolar.
