Introduction: All most all metals are unstable when exposed to air. This is because of the tendency of the metal to be converted into its oxidized form on reaction with air. When compared to zinc, iron has a greater tendency to form oxidized form and thus has greater susceptibility to corrosion. The ability of metals to react with air varies and this determines their relative stability. As zinc is much stable when compared to iron, it is used to galvanizing iron pipe, thus preventing contact of iron with air and water that contains dissolved air. Brass is an alloy ...

Introduction

Resistivity is a parameter which defines the resistance of a metal to the flow of electric current per unit volume of the metal (Jones, n.d.). The resistivity exhibited by a metal is dependent on three physical properties; the cross-sectional area, length, and the nature of the material (A´ ngel & Tirado-Miranda, 2009). The value of resistivity dictates the conductivity of a metal, high resistivity is associated with low electrical conductivity while low resistivity means that the metal is a good conductor (The Physics Hypertext Book, n.d.). Therefore, it can be concluded that low resistivity allows for increased movements of electrons within the metal while high ...
