PPT-Galvanic Cell Materials Engineering

Dr Lubna Ghalib Galvanic Cell not one molar with Electrolytes that are Most of electrolyte solutions of the real galvanic cells are not to be 1 mole But they are always dilute solutions which they are less than 1 mole If the ions concentrates in the electrolyte surround to the anode electrode is less than 1 mole the reaction motive force to dissolve or corrode the anode will be higher Because there is less concentrate of ions that causes the reverse reaction There for it will be more negative of electrochemical series on the anodic halfcell .

The range of temperatures experienced will play a large part in the materials selection. Extremes are illustrated by the examples of cryogenic tanks and thermal protection systems for re-entry applications. Temperatures below room temperature generally cause an increase in strength properties, however the ductility decreases. Ductility and strength may increase or decrease at temperatures above room temperature. This change depends on many factors, such as temperature and time of exposure..

THE UNION of physics and chemistry began with the twitching of a frog's leg. In the 1790s Luigi Galvani lay a dead frog on a table. Also on the table was a static electricity generator. An assistant accidentally touched the nerves of the frog with a scalpel and the muscles of the frog contracted . Associate Degree of Applied Engineering . (Renewable Energy Technologies).
