Question
Science Question on Chemical Effects of Electric Current
A tester is used to check the conduction of electricity through two liquids, labelled A and B. It is found that the bulb of the tester glows brightly for liquid A while it glows very dimly for liquid B. You would conclude that
A
liquid A is a better conductor than liquid B.
B
liquid B is a better conductor than liquid A.
C
both liquids are equally conducting.
D
conducting properties of liquid cannot be compared in this manner.
Answer
liquid A is a better conductor than liquid B.
Explanation
Solution
Liquid B is a weaker conductor of electricity than liquid A, so bulb glows dimly in the second case.
(A) Liquid A is a better conductor than liquid B.
