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

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

In its simplest form, it consists of a cylindrical glass tube about 50 cms long, closed at both ends called the discharge tube (or Crookes tube). The tube is fitted with two metallic electrodes, which are connected to a source of high voltage. It is filled with gas and the discharge tube..

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..

Except for gold and platinum nitric acid attacks all metals, forming different products. The product formed depends upon the nature of the metal, concentration of the acid and temperature. Depending upon their reactivity, metals may be grouped as follows: Less active..

. 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..
