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

Living matters are organisms that possess the fundamental characteristics of life. This includes movement‚ respiration‚ sensitivity‚ growth‚ reproduction‚ excretion‚ and nutrition. First off‚ every single living matter is capable of movement. For instance‚ animals can move according to their will; they can change position and transfer from one place to another. Although this trait may not be as noticeable in plants‚ they also show little movements such as when leaves turn towards the direction

Introduction and Hypothesis: Rust is a reddish or yellowish-brown flaky coating of iron oxide that is formed on iron or steel by oxidation‚ especially in the presence of moisture. The rusting process is electrochemical‚ meaning it forms from a chemical reaction which takes place in a solution where there is an electron transfer between the electrode and the electrolyte or species in solution. In the case of rusting‚ the transfer of electrons from iron to oxygen begins the electrochemical process
