Graphene replaced with copper Graphene nanoribbons have a current-carrying capacity two orders of magnitude higher than copper Recent research into the properties of graphene nanoribbons provides two new reasons for using the material for interconnects in future computer chips. In widths as narrow as 16 nm‚ graphene has a current-carrying capacity approximately a thousand times greater than copper while providing improved thermal conductivity. The current-carrying and heat-transfer measurements

When you mix copper‚ silver‚ and nitrate together‚ you will end up with silver nitrate solution will turn blue (it has become copper nitrate). On the piece of copper‚ there would be a coating of solid silver. If a chemical reaction is going to be observed when chemicals are mixed‚ heated or any other means of altering the substance‚ then we will be able to predict the products formed. If it is observed that in the original versus the changed substance no new substances are formed‚ the change is reversible

The discovery of copper does not have an exact date. Copper is said to be a prehistoric element. This element was said to be first discovered around 8000BC. The ancient civilizations started to take the copper out of the ore they found around 4000BC. This is when copper started to be put to good use. Early civilizations discovered that copper is malleable and is sharp. They realized they could make copper into tools and weapons. This was easier than the stone that they were originally using. This
