Match List - I with List- II. ( array |l|l|l|l| & List - I & & List - II (a) & array l Entropy of vapourisation array & (i) & S = negative (b) & array l U in reversible adiabatic expansion of an ideal gas array & (ii) & Decreases (c) & array l Crystalline solid state array & (iii) & Lowest entropy (d) & array l A liquid freezes array & (iv) & H _ vap T _ b array )

Options

  1. A(a) - (iv), (b) - (ii), (c) - (iii), (d) - (i)
  2. B(a) - (iii), (b) - (ii), (c) - (iv), (d) - (i)
  3. C(a) - (iv), (b) - (i), (c) - (iii), (d) - (ii)
  4. D(a) - (iv), (b) - (iii), (c) - (ii), (d) - (i)

Correct answer

A. (a) - (iv), (b) - (ii), (c) - (iii), (d) - (i)

Step-by-step solution

(a) Entropy of vaporization: ( S= H_ vap T ) (matches with iv). (b) ( U ) in reversible adiabatic expansion of an ideal gas: Internal energy decreases in adiabatic expansion (matches with ii). (c) Crystalline solid state: Crystalline solids have the lowest entropy due to their highly ordered structure (matches with iii). - (d) A liquid freezes: Freezing is an exothermic process where entropy decreases (matches with i).
