An alloy is a material composed of two or more metals or a metal and a nonmetal. 

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

An alloy is a material composed of two or more metals or a metal and a nonmetal. An alloy may be a solid solution of the elements (a single phase), a mixture of metallic phases (two or more solutions) or an intermetallic compound with no distinct boundary between the phases. Solid solution alloys give a single solid phase microstructure, while partial solutions exhibit two or more phases that may or may not be homogeneous in distribution, depending on the thermal (heat treatment) history of the material. An inter-metallic compound has one other alloy or pure metal embedded within another pure metal.

A Correct answer
Explanation

Bronze is an alloy consisting primarily of copper, commonly with about 12% tin and often with the addition of other metals (such as aluminium, manganese, nickel or zinc) and sometimes non-metals or metalloids such as arsenic, phosphorus or silicon.

All the alloys are homogeneous mixture.

An alloy is a specific type of substance that can best be described by which of the following?

  1. An alloy is a mixture of various metals that can also contain non-metal elements.

  2. An alloy is a compound made of different types of metals.

  3. An alloy can only contain metals from the transition elements.

A Correct answer
Explanation

Ans : (A) An alloy is a mixture of various metals that can also contain non-metals elements.

Eg : Steel is an alloy of iron (metal) and carbon (non-metal).

Monel metal is a metallic alloy of copper and nickel with $5$% iron. It is used in making:

  1. locks

  2. strong boxes

  3. almirahs

  4. motor parts
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Monel is a group of nickel alloys, primarily composed of nickel (up to 67%) and copper, with small amounts of iron, manganese, carbon, and silicon. Stronger than pure nickel, Monel alloys are resistant to corrosion by many agents, including rapidly flowing seawater.

Being stronger than pure nickle Monel metal is used in making locks.
Hence option A is correct answer.

The filament of an electric bulb is made of :

  1. Carbon

  2. Aluminium

  3. Tungsten

  4. Nickel
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The filament of an electric bulb is made of tungsten because it has some amazing properties including the highest melting point $(3422^oC )$, lowest vapor pressure, and greatest tensile strength out of all the metals. Because of these It can reach high temperature before melting.
