Question

Liquids occupy definite volume but have no definite shape. It takes the shape of the container.
a.) True
b.) False

Answer 1

Hint: Liquids have strong forcer forces of attraction than gas, and weaker than solids. Liquids flow under the influence of unbalanced forces.

Complete step by step answer:
Solids and liquids are collectively called condensed phases because their particles are in virtual contact.
If the particles of a substance have enough thermal energy to partially overcome intermolecular attractive interactions, then the particles can move about each other while remaining in contact.
This describes the liquid state. In liquids, the particles are in sort of close contact, so liquids have a definite volume. But, since the particles can move about each other freely, the liquids have no definite shape and take a shape dictated by its container.
So, the correct answer is “Option A”.

Additional Information:
The amorphous solids also have a tendency to flow, though very slowly. Therefore, sometimes they are called pseudo solids or super cooled liquids. For example, Glass panels fixed to windows or doors of old buildings are sometimes after a period of decades slightly thicker at the bottom than at the top. This is because the amorphous glass flows down very very slowly and makes the bottom portion slightly thicker than the upper portion.

Note: Liquids are ever so slightly compressible, but they still have definite volume, definite doesn’t mean fixed, the compression and extension change a small amount of volume, but it by a very small fraction of original, that is too in extreme lab conditions, so volume is considered definite.
