Which statement is generally considered correct for brass?
Answer and explanation
Correct answer: It is a solid-in-solid solution
Brass is a homogeneous alloy made mainly by combining copper and zinc. Both metals are solids, and the resulting alloy is also solid at room temperature. In terms of the physical states of its components and medium, brass is therefore classified as a solid-in-solid solution. The other choices describe gas-liquid, liquid-gas or solid-liquid systems, not brass.
