Copper...pennies...NEAT!!!

Copper has many different propreties, or descriptions of what is in it or what it does.

Chemical Properties of Copper:
    Heat of Fusion: 134 J/g
    Heat of Vaporization: 3630 J/g
    Heat of Sublimination       at 1025.85 C: 3730 J/g
 
Physical Properties of Copper:
   Melting Point: 1084.6C
    Boiling Point: 2567C
    Density at 26.85 C: 8.96 g/cc
    Physical Matter: Solid
    Optical Reflectivity: 90%
    Flammibility Class: non-combustable solid, unless rust

Copper's magnetic state is diamagnetic.
Copper is also biostatic.


Reactivity of Copper
  • absorbs atomic oxygen species
  • does not associate with molecular oxygen species
  • clusters react when evaporated onto a carbon substrate
  • does not react with steam, water, or diulte acid
  • can be oxidized by concentrated sulfuric and nitric acids

Hazards of Copper
  • Copper sulfate can irritate skin, eyes, nose, and throat; affects liver if inhaled or swallowed
  • can cause allergic skin rashes
  • lowest observed toxic dose is 120 g/kg
  • causes gastrointestinal effects
