Two solid pieces, one of steel and the other of aluminium when immersed completely in water have equal weights. When the solid pieces are weighed in air
- A the weight of aluminium is half the weight of steel
- B steel piece will weigh more
- C they have the same weight
- D aluminium piece will weigh more
Answer & Solution
Correct Answer
(A) the weight of aluminium is half the weight of steel
Step-by-step Solution
Detailed explanation
In air, force of gravity acts on metals. Thus, these have their actual weight. Atomic weight of steel, ie, iron is 56 and that of aluminium is \(27 .\) Hence, it can be said that in air the weight of aluminium is half the weight of steel.
