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 sate 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 a mixture of free electrons and ions whereas state E is named after an Indian scientist and a famous Physicist. (a) Name the physical states (i) A (ii) B (iii) C (iv) D and (v) E. (b) Name one substance belonging to state C which can directly change into vapours on heating. What is this process known as? (c) Name one substance which normally belongs to state B but whose solid form changes directly into a gaseous state. (d) Name the most common substance belonging to state A. (e) Which state of matter makes the sun and other stars to glow? |
