Which law states that the entropy of an isolated system always increases? (2021)

Step 1: Understand what entropy means. Entropy is a measure of disorder or randomness in a system.
Step 2: Learn about isolated systems. An isolated system does not exchange energy or matter with its surroundings.
Step 3: Know the laws of thermodynamics. There are four laws, and they describe how energy behaves.
Step 4: Identify the second law of thermodynamics. This law specifically states that in an isolated system, entropy tends to increase over time.
Step 5: Conclude that the second law of thermodynamics is the answer to the question.
