Questions & Step-by-Step Solutions
What happens to the entropy of a system when it undergoes a spontaneous process?
Correct Answer: Entropy increases
Step 1: Understand what entropy is. Entropy is a measure of disorder or randomness in a system.
Step 2: Know what a spontaneous process is. A spontaneous process is a natural process that occurs without needing to be driven by an external force.
Step 3: Recognize that in a spontaneous process, systems tend to move towards a state of higher disorder.
Step 4: Conclude that as a system becomes more disordered during a spontaneous process, its entropy increases.
Entropy and Spontaneity – Entropy is a measure of disorder in a system, and in a spontaneous process, the total entropy of the system and its surroundings tends to increase.
