To Show that Liquids do not have a Fixed Shape but they have a Fixed Volume
Water is a liquid, so we will use water in this experiment. We take some water in a beaker and mark the level of water in it (see Figure 23(d)]. We will find that water takes the shape of the beaker. We pour this water from the beaker into other containers (or vessels) of different shapes, one by one.
First we pour the water from beaker into a glass tumbler. We will find that water takes the shape of the glass tumbler [see Figure 23(b)]. Then we pour this water in a conical flask. We will find that the same water now takes the shape of a conical flask [Figure 23(c)]. And finally we pour the water from conical flask into a flat-bottomed flask. The water now takes the shape of a flat-bottomed flask [Figure 23(d)]. From this experiment we conclude that water has no fixed shape of its own, it takes the shape of the container (or vessel) in which it is poured. In general, we can say that "A liquid has no fixed shape. It takes the shape of its container".
Now, let us pour the water from the flat-bottomed flask back into the original beaker. We will find that water fills the beaker up to the same mark. This means that there is no change in the volume of water when it is poured into different containers. From this we conclude that water has a fixed volume which does not change on changing the container. In general we can say that "A liquid has a fixed volume".
