b) Describe how adding zinc affects the melting point of the mixture
Answers
Answer:
Thus copper melts at 1,083�C, while zinc melts at 419�C and boils at 907�C So, in making brass, if we just put pieces of copper and zinc in a crucible and heated them above 1,083�C, both the metals would certainly melt.

Answer:
Zinc has very minor effect on the thermal conductivity of copper, followed by increasing effects from nickel, tin, manganese, silicon, and serious effects from phosphorus. Phosphorus is often used to deoxidize copper, which can increase the hardness and strength, but severely affect the conductivity.
