Figure 1	Figure 2	Figure 3

The arrangement of particles in three different phases of matter is shown above.

1. Which state is represented by Fig. 1?
2. In which state will the inter-particle attraction be maximum?
3. Which one of them cannot be contained in an open vessel?
4. Which one can take the shape of its container?

Answer 1

1. The liquid state is represented by Fig 1.
2. In Fig. 3 the inter-particle attraction will be maximum because it is in a solid state.
3. Fig. 2 cannot be contained in an open vessel, as it is in a gaseous state.
4. Fig. 1 can take the shape of its container, as it is in a liquid state.
