Q.

The scientists now say that there are actually five states of matter A, B, C, D and E. The state A has a fixed volume but no fixed shape. The state B neither has fixed volume nor fixed shape and state C has a fixed shape as well as a fixed volume. The state D in which particles exist in ionised state at higher temperatures whereas state E is named after an Indian scientist and a famous Physicist. Identify A, B, C, D, and E.
