                                     Figure 1   Types of matter



             The first picture shows stones of different sizes. The second
             picture shows jugs of the same size filled  with water to different

             levels. The third picture shows balloons of different sizes filled
             with air.


             The mass of an object differs based on its size. For example,

             a large stone is heavier than a small one. A big item occupies
             more space than a small one. Let us take an example of air. It
             can be stored in things such as balloons. The more you pump
             air into the balloon, the bigger it becomes. Therefore, the
             stone, water and air have mass and occupy space.



             Look at the following pictures and identify their states of
             matter.
