3. Elemental mercury is a liquid under standard ambient temperature and pressure conditions. The standard molar entropy of liquid elemental mercury is 76.02 J K mol", its mass density is found to be 5.43 g cm?, and its molar mass is 200.59 g mol1 (a) How much does the chemical potential of liquid mercury change when it is heated from 298 k to 394 K at a constant pressure of 1 bar. [1 mark] (b) Relative to its initial chemical potential in (a) (i.e., prior to heating) did heating create a more stable phase or a less stable phase, why? [1 mark] (c) if elemental liquid mercury experiences a pressure increase from 1 bar to 10 bar, by how much does the chemical potential change? [2 marks] (d) Relative to its initial chemical potential in (c) (i.e., prior to the pressure increase) did the increase in pressure create a more stable phase or a less stable phase, why? [1 mark]
