Properties of Water

Chevelle is cleaning her kitchen and notices that water can dissolve sugar, salt, and many other substances she uses. Why is water called a universal solvent?

• It can be found anywhere

• It freezes when it gets cold

• It floats when frozen

• It dissolves most substances

Baylin carefully places a paper clip on the surface of water and notices that it floats without sinking. The tightness across the surface of water that enables the paper clip to float is ____________.

• adhesion

• capillary action

• surface tension

• polarity

When Austin notices that water droplets on a window tend to merge together rather than spread apart, what property of water is he observing?

• Cohesion

• Adhesion

• Capillary Action

• Universal Solvent

When Aimee waters her houseplants, she notices that water droplets cling to the leaves. This is an example of adhesion. What does adhesion mean?

• the water molecules stick to each other

• the water molecules stick to other surfaces

• the water molecules are less dense

• the water molecules are far apart

Omar notices that some insects, like water striders, can walk on the surface of a pond without sinking. This is possible because of ____________.

• capillary action

• adhesion

• surface tension

• universal solvent

Tyler notices that when he gently drops small droplets of water onto the surface of a bowl of water, the droplets sometimes bounce before merging. This happens because of surface tension.

• True

• False

Ben notices that when he drops water onto a flat surface, the droplets form a spherical shape (as pictured). This happens because of ____________

• adhesion

• cohesion

• capillary action

• solubility
