from getting rid of extra copper. A small amount of copper obtained from food is needed to stay healthy‚ but too much copper is poisonous. In Wilson disease‚ copper builds up in the liver‚ brain‚ eyes‚ and other organs. Over time‚ high copper levels can cause life-threatening organ damage. Pathophysiology and clinical features of Wilson disease Wilson disease is an autosomal recessive inherited disorder of copper metabolism resulting in pathological accumulation of copper in many organs and tissues

Otzi the Iceman Otzi the Iceman is a nickname given to a very well preserved natural mummy of a man from Europe during the European Copper Age. He is the oldest natural human mummy preserved by freezing and he gives an extraordinary view of the European Copper Age. Otzi the Iceman aided us with an exceptional understanding of the European Copper Age from the equipment he was carrying‚ the cloth he was wearing‚ and the physical remains of his body. A set of well preserved equipments were discovered

Copper is a transitional metal with an atomic number of 29. Its atomic mass is 63.546. A pure metal found in nature‚ its compounds are usually found as copper(II) salts. Copper is typically a reddish-brown with a shine or glow to it. When it is exposed to air it darkens to a brown color. If exposed to air and water‚ it becomes a blue-green. Its phase of matter is solid‚ with a melting and boiling point of 1084.62 °C and 2562 °C respectively. Copper is soft and malleable‚ meaning that it is capable

Introduction The resistance of a wire depends on certain factors. Some of these variables are listed below: Length of wire Diameter or thickness of wire Temperature at which wire is kept The material of which wire is made out of. The potential difference or voltage. Humidity Cross sectional area. Voltage across circuit All these factors will have to be kept constant except the diameter of the wire whilst doing the experiment to ensure that the investigation is

electrical energy. In the potato battery‚ there is a transfer of electrons between the zinc coating the galvanized nail that will be inserted into the potato and the copper wire that will be inserted another part of the potato. The potato conducts electricity‚ yet keeps the zinc ions and copper ions separate‚ so that the electrons in the copper wire are forced to move (generate current). It’s not enough power to shock you‚ but the potato can run a small digital clock. Materials for a Potato Clock You
