Questions & Step-by-Step Solutions
The entropy of a perfect crystalline substance at absolute zero is given by which law?
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.
Step 3: Know what a perfect crystalline substance is. A perfect crystalline substance has a highly ordered structure with no defects.
Step 4: Familiarize yourself with the third law of thermodynamics. This law states that as the temperature of a perfect crystalline substance approaches absolute zero, its entropy approaches zero.
Step 5: Conclude that the third law of thermodynamics explains the behavior of entropy at absolute zero.
