Calculate the change in entropy when one mole of metallic aluminum is heated at one bar pressure from an initial temperature of 25 °C to a final temperature of 750 °C. The molar heat capacities of solid and liquid aluminum at one bar pressure are 29.2 J mol-1 k-and 31.75 J mol-1 k1, respectively. The specific enthalpy of fusion of aluminum at its melting point (660.46 °C) is 396.57 Jg7....

2.00 mol diatomic perfect gas molecules, for which Cp = 7/2R, is changed from 25°C and 1.50 atm to 135°C and 7.00 atm. Without doing any calculations, is the change in temperature or the change in pressure more important in determining the overall change in entropy (of the system)? Why? What can you conclude about the sign of ΔSsys . Calculate ΔSsys for the change.
