Questions & Step-by-Step Solutions
Which of the following statements is true about the second law of thermodynamics?
Correct Answer: The total entropy of an isolated system can never decrease over time.
Step 1: Understand what entropy means. Entropy is a measure of disorder or randomness in a system.
Step 2: Recognize that the second law of thermodynamics deals with energy and entropy in isolated systems.
Step 3: Learn that an isolated system is one that does not exchange energy or matter with its surroundings.
Step 4: Remember that the second law states that the total entropy in an isolated system will either increase or stay the same over time, but it will never decrease.
Step 5: Conclude that this means systems naturally progress towards more disorder or randomness.
