7. GAS The gaseous state of matter is found between the liquid and plasma states, the latter of which provides the upper temperature boundary for gases At a low temperature gas molecules travel, on the average, at slower speeds than they travel at a high temperature. So, at a low temperature the molecules have, on the average, less kinetic energy than they do at a high temperature. Lower speeds, lower kinetic energies. Gases are random groups of atoms

8. PLASMA Plasma is a state of matter similar to gas in which a certain portion of the particles are ionized. The basic premise is that heating a gas dissociates its molecular bonds, rendering it into its constituent atoms. Further heating leads to ionization , turning it into a plasma: containing charged particles, positive ions and negative electrons. The presence of a non-negligible number of charge carriers makes the plasma electrically conductive so that it responds strongly to electromagnetic fields

9. BOSE-EINSTEIN CONDENSATE A Bose–Einstein condensate (BEC) is a state of matter of a dilute gas of weakly interacting bosons confined in an external potential and cooled to temperatures very near absolute zero (0 K or −273.15 °C). Under such conditions, a large fraction of the bosons occupy the lowest quantum state of the external potential, at which point quantum effects become apparent on a macroscopic scale. This state of matter was first predicted by Satyendra Nath Bose and Albert Einstein in 1924–25
