Question: The entropy of a perfect crystal at absolute zero temperature is given by which law?

Options:

Correct Answer: Third law of thermodynamics

Solution:

The third law of thermodynamics states that the entropy of a perfect crystal approaches zero as the temperature approaches absolute zero.

The entropy of a perfect crystal at absolute zero temperature is given by which law?

The entropy of a perfect crystal at absolute zero temperature 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 or -273.15 degrees Celsius.
Step 3: Know what a perfect crystal is. A perfect crystal is a solid where all the atoms are arranged in a perfectly ordered structure.
Step 4: Familiarize yourself with the third law of thermodynamics. This law states that as the temperature of a perfect crystal approaches absolute zero, its entropy approaches zero.
Step 5: Conclude that the third law of thermodynamics explains the relationship between entropy and temperature for a perfect crystal.

Third Law of Thermodynamics – This law states that the entropy of a perfect crystal approaches zero as the temperature approaches absolute zero.
