Question

Shivam made some iron sulfide and placed it in a circuit with a cell and a lamp.
(a)What property was he investigating?
(b) What did he conclude?
Shivam then tested iron and sulfur separately in the circuit.
(c) What happened when he tested the iron? Explain your answer.

Answer 1

Answer:

a) He is investigating the property of electrical conduction of the iron sulfide solution

b) He will conclude that the solution is electrically conducting in nature

c) When the experiment is only conducted by iron then also the bulb will glow and show the conductivity of iron

Explanation:

a) When we use the lamb and cell and the given solution then the solution is the medium through which the electric current will flow

If the medium is not conducting in nature then lamp will not glow while if the lamp is glowing then it will glow.

b) When we use the solution of iron sulfide then due to conducting nature of iron it will easily conduct electrical current through it

So the lamp will glow

c) Since we know that the iron is electrically conducting in nature so when the experiment is done only with iron then also it will show the lamp glow
