Questions & Step-by-Step Solutions

Which law states that the entropy of an isolated system never decreases? (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 main laws, and they describe how energy behaves.
  • Step 4: Identify the second law of thermodynamics. This law specifically talks about entropy.
  • Step 5: Remember the key point of the second law: it states that the entropy of an isolated system never decreases over time.
