Expert Solution
Step 1

As per the norms of the company, only first 3 parts will be answered. For the fourth and fifth part, kindly upload it as a separate question.

Step 2

A.16: Answer is FALSE

Copper alloys posses a high degree of toughness and ductility at low temperatures.

Copper alloys attains more strength and more ductility as the temperature goes down.

A.17 Answer is TRUE

The selection of a material is carried out based upon the specifications such as

1.Name

2.Chemical, biological and physical properties

3. Composition of the material.

4. Method of manufacturing

5. Manufacturer.

Thus it can be said that Set of specifications is a step in criteria for selection.
