Questions & Step-by-Step Solutions
In which process does the entropy of the system decrease?
Step 1: Understand what entropy means. Entropy is a measure of disorder or randomness in a system.
Step 2: Know that when a substance changes from a more disordered state to a more ordered state, its entropy decreases.
Step 3: Identify the process of freezing. Freezing is when a liquid turns into a solid.
Step 4: Recognize that when water freezes, its molecules become more organized and form a solid structure (ice).
Step 5: Conclude that during the freezing of water, the entropy of the system decreases because it goes from a liquid (more disorder) to a solid (less disorder).
