What happens to the entropy of an isolated system? (2020) 2020
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: Familiarize yourself with the second law of thermodynamics. This law states that in an isolated system, the total entropy can never decrease over time.
Step 4: Conclude that in an isolated system, entropy will either increase or stay the same, but it will not decrease.
Entropy in Isolated Systems – Entropy is a measure of disorder or randomness in a system, and in an isolated system, it tends to increase over time according to the second law of thermodynamics.
