Question

sti on 18 of 25 Incorrect Incorrect Sapling Learning Ma Water is a polar molecule that exhibits the properties of adhesion and cohesion. Match the examples to the appropriate category. Cohesiorn Both cohesion and adhesion Adhesion ater sticks to the surface of a membrane Some insects can float on the water's surface due to Blood flows up a narrow tube as a nurse collects a blood sample h surface tension. ater forms into a drop on a leaf and hangs down but it does not drop Incorrect. One or more items are misplaced. When a drop of water hangs from a leaf, the water rgolecules are adhering to the leaf, and they are also sticking to each other. Choose a better category for this example.

Explanation / Answer

Cohesion: Some insects can float on the waters surface due to high surface tension

Both cohesion and adhesion: blood flows a narrow tube as a nurse collects a blood sample

Water forms into a drop on a leaf and hangs down, but it does not drop

Adhesion: Water sticks to the surface of a membrane
