Examine the incomplete statement.

Liquids have a _[blank]_ shape and _[blank]_ volume.

Which words best complete the statement?

fixed; fixed

variable; variable

variable; fixed

fixed; variable

variable, fixed

Answer: Option (c) is the correct answer.

Explanation:

In liquids, molecules are held by slightly less strong intermolecular forces of attraction as compared to solids.

Hence, molecules of a liquid are able to slide past each other as they have more kinetic energy than the molecules of a solid.

As a result, liquids are able to occupy the shape of container in which they are placed. Also, liquids have fixed volume but no fixed shape.

Thus, we can conclude that liquids have a variable shape and a fixed volume.
