Questions and Answers

What is the reason behind the spark or crackle we experience when taking off synthetic clothes in dry weather?

  • Static electricity generated by movement
  • Accumulation of electric charges due to rubbing of insulating surfaces (correct)
  • Chemical reaction with air when removing the clothes
  • Presence of metal fibers in synthetic clothes

    • What phenomenon is responsible for the electric shock when opening the door of a car or holding a bus's iron bar after sliding from a seat?

  • Friction between clothes and metal objects
  • Chemical reaction with metal surfaces
  • Discharge of accumulated electric charges through the body (correct)
  • Presence of magnetic fields around vehicles

    • Why do we experience a sensation of an electric shock in specific situations like those described in the text?

  • Because of the presence of lightning in the atmosphere
  • Due to rubbing of insulating surfaces accumulating electric charges (correct)
  • As a reaction to sudden temperature changes
  • Resulting from the movement of air molecules around us
