To show that liquids take up the shape of the container
Take two flasks of different shapes. Now fill up each flask with water. What do you notice? The water takes up the shape of the container. What do you understand from this? Liquids placed in containers of different shapes take up the shape of the container.
of the container
A liquid, such as water is not hard but occupies a definite (fixed) space. However, it does not have a definite (fixed) shape and it takes up the shape of the container in which it is kept.
A liquid cannot be compressed much. A liquid is relatively incompressible fluid. It has fixed volume but no fixed shape. In substances, where the intermolecular attractive forces are relatively weak, they are not so tightly packed, and hence the spaces between them are relatively large. Therefore, the molecules can have easy movement.
However, the molecular motion is not great enough to completely overcome the forces of attraction between molecules. So the molecules stay together. Such substances are in the liquid state. The molecules in the liquid state are not too tightly packed. The intermolecular distance is more than that in solids. Liquids can therefore be compressed to some extent but not so easily.
