  4. Compressibility
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Surface tension is the property that causes the surface of a liquid to behave like a stretched elastic membrane. It is responsible for the formation of waves on the surface of a liquid.

Multiple choice
