simple experiment that copare conduction in three metals: iron silver and copper

Metals are good conductors because they have free electrons. Silver is the best conductor of heat and electricity. Lead is the poorest conductor of heat. Bismuth, mercury and iron are also poor conducto..

. Aluminium does not oxidise (corrode) as quickly as its reactivity would suggest. Once a thin oxide layer of (Al 2 O 3 ) has formed on the surface, it forms a barrier to oxygen and water and so prevents further corrosion of the aluminium. Aluminium is a useful structural metal...

They are generally solids with characteristics such as hardness, malleability, ductility high tensile strength, lustre and ability to conduct heat and electricity. For example: Copper, iron, zinc e..

Procedure Observation Inference Take a table tennis ball and make 3 slits into it The force of the steam rotates the blades, and it acts like a simple turbine. Mechanical energy is converted into electrical energy. Fix semicircular fins of a metalh..

This is the most convenient method used for the purification of a number of metals e.g., copper, silver, gold, zinc, aluminium, nickel etc. The crude (impure) metal is made the anode and a thin sheet of pure metal is made the cathode. The electroly..

. The major problem of corrosion occurs with iron (or steel) as it is used as a structural material in industries like construction, infrastructure, bridges, rail transport power transmission, shipbuilding, automobiles, heavy industries etc. Aluminium, another useful structural metal..
