Questions & Step-by-Step Solutions
Which law states that the entropy of a perfect crystal approaches zero as the temperature approaches absolute zero?
Step 1: Understand what entropy is. Entropy is a measure of disorder or randomness in a system.
Step 2: Learn about absolute zero. Absolute zero is the lowest possible temperature, where all molecular motion stops, and it is 0 Kelvin or -273.15 degrees Celsius.
Step 3: Know what a perfect crystal is. A perfect crystal is a solid where the atoms are arranged in a highly ordered structure.
Step 4: Connect the concepts. The Third Law of Thermodynamics tells us that as we cool a perfect crystal down to absolute zero, its disorder (entropy) decreases.
Step 5: Conclude that at absolute zero, a perfect crystal has no disorder, meaning its entropy approaches zero.
