Look at the diagram below and answer the question that follows: The molecular arrangement of which state of matter is represented by figure ' A ' ?

In the figure ' A ' , the particles are far apart. On applying pressure, these particles can be brought closer. Hence, the molecular arrangement shows the gaseous state of matter.

Look at the diagram below and answer the question that follows: The molecular arrangement of which state of matter is represented by figure ' B ' ?

In figure ' B ' , the particles are closely held to each other. These particles vibrate in their own positions. On applying heat, their kinetic energy also increases and there will be a change in its state of matter. Hence, the molecular arrangement represents solid.
