Problem

Two identical, rigid 1.0 L flasks each contain exactly 1.0 mol of liquid water. Flask 1 is at 25 °C and Flask 2 is at 80 °C. Assume that all of the water in both flasks remains in the liquid phase and that density changes with temperature are negligible. (a) Identify which flask contains the water with the greater molar entropy. (b) Justify your answer to part (a) by discussing the molecular-level motion and energy distribution of the water molecules in each flask as described by kinetic molecular theory.
