A child staying in coastal region tests the drinking water and also the seawater with his tester. He finds that the compass needle deflects more in the case of seawater. Can you explain the reason?
Answers
Solution:
Sea water contains a huge amount of dissolved salts in comparison to drinking water.
Hence, sea water has more conductivity of electricity.
It produces a stronger magnetic field in the wire.
Hence, the compass needle deflects more in the case of seawater
Answer:
A water is colourless, odourless and transparent liquid which is a molecule that contains two hydrogens and one oxygen atom. Water can conduct electricity because it contains different kinds of impurities as well as ions. The drinking water comprises less dissolve salt as compared to the seawater, which has more dissolved salts in it. Electricity can quickly transfer through seawater than drinking water. The amount of diffused salt causes the needle of the compass to deflect.
