Question

Sort these liquids top to bottom in the increasing order of the amount of deflection shown in the magnetic compass when each of them is connected in an electric circuit.

Answer 1

The amount of deflection shown in the magnetic compass depends on how good conductor a particular liquid is. Among the given liquids, distilled water is the poorest conductor and mercury is the best conductor of electricity. Hence, the correct order would be:
Mercury > Lemon juice > Tap water > Distilled water
