Cu Copper L 3.950 Cu Copper 2.723 4. Determine the melting point of copper at a pressure of 90 bar. Use the melting point at atmospheric pressure and the associated enthalpy of fusion, as well as the densities and heat capacities of solid and liquid copper for this calculation. Properties of copper not listed in Table A.2.3 of the book may be found in the online version of the CRC Handbook of Chemistry and Physics, which is available through the library webpages. Once in the online version of the CRC Handbook, the "search chemicals" function (Erlenmeyer flask button) may be helpful
