Homework Answers
1. B) 20
The answer is 20. because the cold drawn wire degree % cold work = ratio of differences between intial and final diameter and intial diameter.
= lf - lo * 100 / lo
= 20 - 25 *100 / 20
= 25 %
2. E) i
Cold work used for strengthen materials at low temperature. It describes that the hardness of the metal increases below the temperature of recrystallisation
3. C) L + Ice.
After the temperature gets decreased the remaining phase will be ice and salt water. As soon as the ice formed at -10oC, there will be a formation of thin layer of salt water over the ice. because the water molecules access each other and form a layer.
