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

compound with a solvent (such as water) to produce mobile ions. An ionic compound is fused by heating An electrical potential is applied across a pair of electrodes immersed in the electrolyte. Each electrode attracts ions that are of the opposite charge. Positively charged ions (cations) move towards the electron-providing (negative) cathode. Negatively charged ions (anions) move towards the electron-extracting (positive) anode. In this process electrons are either absorbed or released. Neutral atoms

Doctor’s surgery. There are two types of circuit’s Parallel circuit‚ and Series circuit. First I am going to explain what a circuit is and what the differences they have are. An electric current is a flow of charge. The charges are given energy and made of flow using a cell or a battery. Charges can flow easily through connecting wire. The cell‚ wires‚ lamp and a switch‚ all these components are connected together and make a loop called a circuit. Current will only flow through a component if there
