Questions & Step-by-Step Solutions

What is the entropy change when 1 mole of ice at 0°C is converted to water at 0°C?
  • 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.
