How does the entropy of the system change in the following processes? (a) the melting of ice cubes at 10 ∘c and 1 atm pressure; (b) separating a mixture of n2 and o2 into two separate samples, one that is pure n2 and one that is pure o2; (c) alignment of iron filings in a magnetic field; (d) the reaction of sodium metal with chlorine gas to form sodium chloride; (e) the dissolution of hcl(g) in water to form concentrated hydrochloric acid.
