What is an alloy?

  1. A mixture of two or more metals.

  2. A mixture of a metal and a non-metal.

  3. A pure metal.

  4. A compound of two or more metals.


Correct Option: A
Explanation:

An alloy is a mixture of two or more metals, or a metal and a non-metal, that has metallic properties. Alloys are often stronger, harder, and more durable than the pure metals they are made from.

What is the most common alloy?

  1. Steel

  2. Bronze

  3. Brass

  4. Aluminum alloy


Correct Option: A
Explanation:

Steel is the most common alloy, and it is made from iron and carbon. Steel is used in a wide variety of applications, including construction, automotive, and manufacturing.

What are the properties of alloys?

  1. Strength, hardness, and durability.

  2. Electrical conductivity and thermal conductivity.

  3. Corrosion resistance and wear resistance.

  4. All of the above.


Correct Option: D
Explanation:

Alloys have a variety of properties, including strength, hardness, durability, electrical conductivity, thermal conductivity, corrosion resistance, and wear resistance.

What are some examples of alloys?

  1. Steel, bronze, and brass.

  2. Aluminum alloy, titanium alloy, and magnesium alloy.

  3. All of the above.

  4. None of the above.


Correct Option: C
Explanation:

Alloys include steel, bronze, brass, aluminum alloy, titanium alloy, and magnesium alloy.

What are alloys used for?

  1. Construction

  2. Automotive

  3. Manufacturing

  4. All of the above.


Correct Option: D
Explanation:

Alloys are used in a wide variety of applications, including construction, automotive, and manufacturing.

What is the difference between an alloy and a compound?

  1. An alloy is a mixture of two or more metals, while a compound is a chemical combination of two or more elements.

  2. An alloy has metallic properties, while a compound does not.

  3. An alloy is stronger than a compound.

  4. All of the above.


Correct Option: D
Explanation:

An alloy is a mixture of two or more metals, while a compound is a chemical combination of two or more elements. Alloys have metallic properties, while compounds do not. Alloys are often stronger than compounds.

What are some of the factors that affect the properties of an alloy?

  1. The composition of the alloy.

  2. The heat treatment of the alloy.

  3. The mechanical working of the alloy.

  4. All of the above.


Correct Option: D
Explanation:

The composition of the alloy, the heat treatment of the alloy, and the mechanical working of the alloy all affect the properties of an alloy.

What are some of the advantages of using alloys?

  1. Alloys are stronger than pure metals.

  2. Alloys are harder than pure metals.

  3. Alloys are more durable than pure metals.

  4. All of the above.


Correct Option: D
Explanation:

Alloys are stronger, harder, and more durable than pure metals.

What are some of the disadvantages of using alloys?

  1. Alloys can be more expensive than pure metals.

  2. Alloys can be more difficult to work with than pure metals.

  3. Alloys can be more susceptible to corrosion than pure metals.

  4. All of the above.


Correct Option: D
Explanation:

Alloys can be more expensive, more difficult to work with, and more susceptible to corrosion than pure metals.

What is the purpose of alloying?

  1. To improve the strength of a metal.

  2. To improve the hardness of a metal.

  3. To improve the durability of a metal.

  4. All of the above.


Correct Option: D
Explanation:

Alloying is used to improve the strength, hardness, and durability of a metal.

What are some of the applications of alloys?

  1. Construction

  2. Automotive

  3. Manufacturing

  4. All of the above.


Correct Option: D
Explanation:

Alloys are used in a wide variety of applications, including construction, automotive, and manufacturing.
