It is equal to -273.15 degrees Celsius, -459.67 degrees Fahrenheit, and 0 kelvin.Įntropy is a degree of disorder or randomness of a system. The temperature is known as absolute zero, and it’s the lowest possible temperature. The temperature at which all particle motion almost stops. Whenever asked to explain the third law of thermodynamics it is necessary to mention the pure crystal state of the matter. Entropy is the measure of the disorder in a system, and while a perfect crystal is by definition perfectly ordered so that the entropy of that crystal is zero.
The 3rd law of thermodynamics explains entropy. The third law of thermodynamics states that the entropy of a pure crystal at absolute zero is zero. The confined study of chemical changes and chemical substances only, the restricted branch of thermodynamics is known as chemical thermodynamics. The bench of chemical science which deals with the study of different forms of energy and the quantitative relationships between them is known as thermodynamics.
