Options:
It decreases
It remains constant
It increases
It can either increase or decrease

Questions & Step-by-Step Solutions
What happens to the entropy of an isolated system?
Step 1: Understand what an isolated system is. An isolated system does not exchange energy or matter with its surroundings.
Step 2: Learn about entropy. Entropy is a measure of disorder or randomness in a system.
Step 3: Know the second law of thermodynamics. This law states that in an isolated system, the total entropy can never decrease.
Step 4: Realize that over time, the entropy of the isolated system will either increase or stay the same, but it will not decrease.
Step 5: Conclude that the entropy of an isolated system always increases, leading to more disorder.
Entropy – Entropy is a measure of the disorder or randomness in a system, and in an isolated system, it tends to increase over time.
Second Law of Thermodynamics – This law states that the total entropy of an isolated system can never decrease over time, and it will tend to increase until it reaches a maximum value.
