Copper normally melts at 1085 °C with an enthalpy of melting of 13.05 kj/mole. The constant molar volumes of liquid and solid copper are 8×10^-6 and 7.6×10^-6 m^3, respectively. a) Estimate the change in melting point if the pressure on copper is increased 10 atm. (Use Clapeyron equation) b) Draw G vs. P graphs for solid and liquid copper (show them on the same graph) at a given constant temperature. Indicate the slopes.
