Question
Chapter 19, Problem 94A
Interpretation Introduction
Interpretation:
The processing and usage of copper in older civilizations is to be compared with the modern times.
Concept introduction:
There are many differences in the processing and usage of copper in the different timelines due to lifestyle changes and access to different resources.
Expert Solution & Answer
Answer to Problem 94A
In the ancient times, copper was obtained from its ore by simply melting the rocks with traces of the metal in it. The usage of copper in ancient times was for weapons, utensils, work tools and sculpture.
In the modern times, the ores are refined and various chemical and electrolytic processes are used for obtaining pure copper. In the modern times copper finds its usage in wiring and statues primarily.
Explanation of Solution
The difference in the processing of copper during the different timelines was due to the advancement of science and technology in the modern times which led to the discovery of better processing methods for metals.
The usage of copper was different because other metals were scarce in ancient times so most objects that needed strength were made up of copper. Also wires did not have a use in the ancient times.
