Match the following with the correct uses.
- a-iv, b-ii, c-iii, d-i
- a-iii, b-iv, c-i, d-ii
- a-i, b-ii, c-iii, d-iv
- a-iv, b-ii, c-i, d-iii
Hint:
An alloy is a substance which is formed when two or more metals are combined. They can also be formed when metals are combined with other elements. However, the properties which alloys exhibit are different from the individual properties of these elements.
The correct answer is: a-iv, b-ii, c-iii, d-i
- Type metal, alloy of lead, antimony, and tin used to make type characters for printing. By varying the proportions of the metals, the desired properties are produced for different kinds of typecasting and printing processes.
- Solder is a metal alloy used to create strong permanent bonds; such as copper joining in circuit boards and copper pipe joints.
- Invar has very low coefficient of expansion and hence, used for making meter
- In the food and catering industry, stainless steel is used to manufacture kitchen accessories, cookware, and cutlery
- a-iv, b-ii, c-iii, d-i
