CORROSION  When a metal is attacked by substances around it such as moisture, acids, etc., it is said to corrode and this  process is called corrosion.  The black coating on silver and the green coating on copper are other examples of corrosion.  Corrosion causes damage to car bodies, bridges, iron railings, ships and to all objects made of metals,  specially those of iron Rancidity  When fats and oils are oxidised, they become rancid and their smell and taste change.  Usually substances which prevent oxidation (antioxidants) are added to foods containing fats and oil.   Keeping food in air tight containers helps to slow down oxidation.  chips manufacturers usually flush bags of chips with gas such as nitrogen to prevent the chips from getting  oxidised Importance of pH in Everyday Life  Our body works within the pH range of 7.0 to 7.8. Living organisms can survive only in a narrow range of  pH change.  When pH of rain water is less than 5.6, it is call...

 Magnetic Effects of Electric Current  A compass needle is a small magnet. Its one end, which points towards north, is called a north pole, and  the other end, which points towards south, is called a south pole.  An electromagnet consists of a core of soft iron wrapped around with a coil of insulated copper wire  A generator converts mechanical energy into electrical energy. It works on the basis of electromagnetic  induction  In our houses we receive AC electric power of 220 V with a frequency of 50 Hz.  One of the wires in this supply is with red insulation, called live wire.  The other one is of black insulation, which is a neutral wire. The potential difference between the two is  220 V.  The third is the earth wire that has green insulation and this is connected to a metallic body deep inside  earth. It is used as a safety measure to ensure that any leakage of current to a metallic body does not give  any severe shock to a user. FUSE  A fuse in...

  SOUND  Sound waves are characterised by the motion of particles in the medium and are called mechanical waves.  When a vibrating object moves forward, it pushes and compresses the air in front of it creating a region of high pressure. This region is called a compression  When the vibrating object moves backwards, it creates a region of low pressure called rarefaction (R), It cannot travel through vacuum, a transverse wave is the one in which the individual particles of the medium move about their mean positions in a direction perpendicular to the direction of wave propagation.  Light is a transverse wave but for light, the oscillations are not of the medium particles or their pressure or density – it is not a mechanical wave.  compressions are regions where density as well as pressure is high.  Rarefactions are the regions of low pressure where particles are spread apart and are represented by the valley, that is, the lower portion of the curve.  A peak is called the crest...
