The 5th state of matter INTRODUCTION Ice is transformed to water at 0°C when the energy of its molecules (particles) increases. Water is similarly transformed to vapor at 100°C (Fig.1). Much stronger zigzag motion of the particles separates and ionizes hydrogen and oxygen i.e. plasma comes into existence (above 13 000 K). Do all bodies fit one of these four states of matter? The answer is: no‚ e.g. the solar corona does not! Fig. 1 The temperature scale. It starts at 0K. Is it infinite long
