Turning copper coins into ‘silver’ and ‘gold’. In this experiment, students observe a copper coin as it is dipped into a solution of sodium zincate in contact with zinc metal. The coin becomes plated with zinc, appearing silver in colour. Students then witness the coin being heated in a Bunsen flame, forming an alloy of brass which
· Resistivity units and conductivity units. Resistivity ρ, unlike resistance, is an intrinsic property of a material.It means that it doesn't matter whether the wire is thick or thin, long or short. The resistivity will always be the same for a specific material, and the resistivity units are "ohm meter" (Ω * m).The higher the resistivity is, the more difficult it is for the current to flow

· Some types of wire are just less forgiving as you work them with your tools. Generally you’ll have better luck with metals like copper and sterling silver as opposed to craft wires which are usually alloyed base metals. Hope that helps! ~ Jess. Reply. Michelle says. October 15, 2016 at 6 26 pm.

· How Does Work Hardening Work? Non-scientific explanation Without getting overly scientific, just consider that any time we are working with wire and moving itwhether through bending, twisting, pulling, coiling, hammering, etc.we are moving the metal’s molecules and squishing them closer and closer together.
Allow the wire to sit in the boiling water for 10 minutes. Remove the copper wire from the water while wearing gloves. Hold the wire with one hand, tightly and use your free hand to grip the plastic on the wire, and then start pulling. The plastic will slide right off the wire but you have to move fast so that the plastic does not get to cool.
