Thermodynamics

2. Third Law of Thermodynamics: As the temperature of a system approaches absolute zero (0 Kelvin), the entropy of a perfect crystal approaches zero. This law implies that it’s impossible to reach absolute zero in a finite number of steps.

Thermodynamics is crucial in many fields, including chemistry, engineering, and even cosmology, as it helps explain phenomena from the operation of engines and refrigerators to the behavior of gases and the dynamics of stars.
