Pressure volume (P-V) calculations of FCC metals (Copper, Silver, Gold, Aluminum and Nickel) have been carried out by taking simple two body Kuchhal and Das (K. D.) and Morse potential. In case of K. D. potential, the computed results of P-V calculations are fairly close with experimental results. At high relative volume, the computed results with Morse potential are closely match with experimental results but at low relative volume, calculated and experimental results are poor match. Our study shows that computed results with K. D. potential gives better results of P-V calculations for all FCC metals in comparison to computed results with Morse potential.
