To Show that Gases do not have a Fixed Shape or a Fixed Volume
Air is a gas, so we will use air in this experiment. We take two balloons of different shapes and sizes.Let us fill equal amount of air in both the balloons. We will find that the air takes the shape of the balloon in which it is filled. For example, in Figure 25(a), the balloon has a round shape so the air takes the round shape of the balloon. In Figure 25(b), the balloon has a long shape, so the air takes the long shape of this balloon. This shows that air has no fixed shape of its own, it takes the shape of the container (here balloon) in which it is filled. In general we can say that "A gas has no fixed shape. It takes the shape of its container". If we look at the round balloon and long balloon shown in Figure 25, we will find that they have different volumes. This shows that the air in the two balloons has different volumes. From this we conclude that the volume of air is not fixed. It takes the volume of the container (here balloon). In general we can say that "A gas has no fixed volume. It takes the volume of its container".
