All elements except hydrogen, which form positive ions by losing electrons during chemical reactions are called metals. Thus metals are electropositive elements. They are characterized by bright lustre, hardness, ability to resonate sound and are excellent conductors of heat an..

The dimensions (in inches) of a rectangular metal sheet are in the ratio 3 : 2. Due to the heat the sheet expanded as shown. Perimeter of the sheet after the expansion is 110 inches. What is the percent increase in the perimeter of the sheet? => 22...

The length and the width of a rectangular metal sheet are 15 in . and 8 in . Find the area of the rectangular metal sheet. => 80 in. 2 or 60 in. 2 or 120 in. 2 or 100 in. 2..

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 electrolyte is usua..

A lathe machine cuts an average length of 16.84 meters of a metal sheet per hour. Find the average length it cuts in 7 hours. => 117.88 meters or 116.88 meters or 111 meters or 116 meters..

Non-metals are the elements in groups 14-18 of the periodic table. Non-metals are not able to conduct electricity or heat very well. As opposed to metals, non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheet..

When a metal sheet of rectangular shape is heated, its length is increasing at 2 cm per second and width at 3 cm per second. Find the rate of change of its area, when its length is 14 cm and width is 12 cm? => 26 cm 2 /sec or 42 cm 2 /sec or 66 cm 2 /sec or 64 cm 2 /sec or 24 cm..

Metals have the ability to withstand hammering and can be made into thin sheets known as foil..

The presence of mobile electrons causes electrical conductivity of a metal. When a potential difference is applied across the metal sheet, the free mobile electrons in the metallic crystal start moving towards the positive electrode. The electrons coming fro..
