why liquids have fixed volume but not fixed shape
Answers
Answer:
Because there are very large intermolecular spaces between and and very less intermolecular forces of attraction between the particles. That's why they are very loosely packed. So, liquids do not have fixed shape.
A liquid has a fixed size because its volume remains constant; no matter what shape it is in, assuming that no more liquid has been added or taken away, there are always the same number of molecules.
Liquids have fixed volume but no fixed shapes because liquid particles are arranged disorderly and are less closely packed together. In liquids particles are not so tightly bound and have spaces in between them and are free to move compared to solids.
The intermolecular forces of attraction between the particles are less strong compared to solids hence liquids does have fixed shape but takes the shape of the container in which it is place i.e. it has fixed volume.
The molecules within a liquid are arranged in such a way that they can freely move around.
This means that unlike a solid, a liquid can continuously change shape.
