Consider the figure shown below in which ice is melted to form water. Which of the following is true regarding this conversion?
|A||Entropy is decreased|
|B||Entropy is increased|
|C||Entropy is not affected since the change does not constitute an actual reaction, but only a change in physical state of H2O|
|D|| Randomness is decreased|
Ans. B The figure shows the conversion of ice (s) to water (l). The process is melting. What happens when a solid is converted to its liquid form? There will be an increase in randomness. This rules out Choice D. Choice C doesn't make any sense. Since the randomness is increased, the entropy is increased.
