Use the SL system state daemon to plot how the specific internal energy u and specific entropy s of aluminum changes with temperature at a constant pressure of 100 kPa (Evaluate three states at, say, 300 K, 700 K, and 1200 K; draw the u-T and s-T diagrams using the pull-down menu. Use the p = c button to see the trend line). Use the Log/Lin buttons to develop a functional relation for u and s in terms of T.
