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 can be compressed very easily by applying pressure and state $C$ has a fixed shape as well as a fixed volume. The state $D$ is mixture of free electrons and ions whereas state E is named after an Indian scientist and a famous physicist.
