Q: What is the entropy change when 1 mole of ice at 0°C is converted to water at 0°C?
Solution:
The phase change from ice to water at 0°C involves an increase in disorder, thus resulting in a positive change in entropy.
Steps: 5
Show Steps
Step 1: Understand that entropy is a measure of disorder in a system.
Step 2: Recognize that ice is a solid and has a more ordered structure compared to liquid water.
Step 3: Note that when ice melts to become water, the structure becomes less ordered, which means more disorder.
Step 4: Identify that this increase in disorder during the melting process leads to an increase in entropy.
Step 5: Conclude that the entropy change when 1 mole of ice at 0°C is converted to water at 0°C is positive.
