Questions & Step-by-Step Solutions
The entropy of a perfect crystalline substance at absolute zero is given by: (2021)
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, 0 Kelvin, where all molecular motion stops.
Step 3: 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 4: Conclude that at absolute zero, a perfect crystalline substance has no disorder, meaning its entropy is exactly zero.
