Question

Brass is a solution of molten copper in
(a) solid zinc
(b) molten zinc
(c) gaseous zinc
(d) molten tin​

Answer 1

Brass is a solution of molten copper in(b) molten zinc

Answer 2

‘Brass’ is a solution of molten copper in Molten zinc.

Answer: Option (b)  

Explanation:  

Brass is an alloy of ‘copper and zinc’. Brass is an alloy made up of copper and zinc. It has higher tensile strength than copper hence making it more rigid. Secondly it is much less reactive than copper hence the durability of the material is increased.  

Thirdly it is not a ‘good conductor’ of heat or electricity like copper hence making it a nice insulator. Also brass has a characteristic lustre, hence it adds a shine which increases the visual appeal.
