Question
Water on wax paper don’t break easily when they touch each other, this is mainly because:
- Molecules in water are small
- Molecules in water are in motion
- Molecules in water are attracted to each other
- Molecules in water are wet
Hint:
The surface tension plays a generous role when it comes to attraction between two different types of molecules.
The correct answer is: Molecules in water are attracted to each other
- Water on wax paper doesn’t break easily when they touch each other, this is mainly because the molecules of water are attracted to each other.
- Surface tension refers to the tendency of the surface of liquids at rest to get shrunken to the minimum surface area that is possible.
- The waxed paper does not absorb the water molecules. It tries to push it away. But the surface tension experienced by the water molecules pulls the molecules together. And as these molecules are attracted to each other, they form a round ball that is capable of sliding over the waxed paper.
Water lingers towards adhesion more than it does towards cohesion.
