What is the third law of thermodynamics? correct answer: The entropy of a perfect crystal is zero. What is the second law of thermodynamics? correct answer: As a whole, the universe always tends towards increasing entropy. What is the relationship between number of microstates and entropy? correct answer: More microstates = higher entropy What is the relationship between temperature and entropy? correct answer: Temperature increases, entropy increases (direct) What is the relatio...
