Answer: The given statement is false.
Explanation:
In gases, the molecules are held by weak Vander waal forces. Hence, they have high kinetic energy due to which they move rapidly from one place to another leading to more number of collisions.
Hence, gases are able to expand more rapidly as compared to liquids.
Therefore, gases will expand to fill their container.
Whereas in liquids, the molecules are held by more strong intermolecular forces of attraction as compared to gases. Due to which they are not able to move much more freely.
Hence, liquids do not expand to fill their container.
Thus, we can conclude that the statement gases and liquids will both expand to fill their container, is false.
