Assignment:
A) Define entropy. Why is entropy considered an absolute quantity?
B) For each of the pairs of substances below, choose the one expected to have the greater absolute entropy. Explain your answer. Assume 1 mol of each substance.
i) Cu(s) or C(graphite) at the same temperature and pressure
ii) Ne(g) at 5.0atm or Ne(g) at 0.10atm, both at the same temperature.
iii) Liquid water or liquid hexane, both at the same temperature and presure.
iv) Ca(s) at 300K or Ca(s) at 500K, both at the same pressure.
Provide complete and step by step solution for the question and show calculations and use formulas.
