Regents Chemistry Exam August 2024 Question 41
41 Which phase change results in an increase in disorder?
(1) I2(g) → I2(s)
(2) Cl2(l ) → Cl2(g)
(3) N2O4(g) → N2O4( l)
(4) H2O(l) → H2O(s)
Solution:
Solid phase is least disordered, followed by liquids, and gases are most disordered. Going from solid to liquid to gas results in an increase in disorder. Choice 2 is the correct answer.
