Question

Which type of mixture is steel?
A. Solid-liquid heterogeneous mixture
B. Solid-solid heterogeneous mixture
C. Solid-solid homogeneous mixture
D. Pure substance

Answer 1

Hint- In such a question, we need to explain the different types of moistures just to specify the material steel, then we need to tell about the basic properties of steel. As explaining briefly about both the components we can easily find our answer.

Complete answer:
Steel is a compound of iron with normally a couple of percent of carbon to improve its quality and crack obstruction contrasted with iron. Numerous other extra components might be available or included. Hardened steels are consumption and oxidation safe and normally need an extra 11% chromium. As a result of its high rigidity and ease, steel is best utilized in structures, framework, apparatuses, ships, trains, vehicles, machines, electrical machines, and weapons. Iron is the base metal of steel and it can take on two crystalline structures (allotropic structures): body focused cubic and face-focused cubic.
Strong homogeneous blends, as vaporous and fluid homogeneous blends, contain various components blended consistently and can't be isolated without any problem. A case of a strong homogeneous blend is bronze, which is a blend of copper and tin.

As steel is a solid homogeneous mixture, thus option C is the correct answer.

Note- The most significant properties of steel are extraordinary formability and sturdiness, great tractable and yield quality and great warm conductivity. Just as these significant properties the most quality of the hardened steel properties is its protection from erosion.
