third law of thermodynamics
Answers
Answer:
The entropy of a perfect crystal is zero when the temperature of the crystal is equal to absolute zero (0 K).
Step-by-step explanation:
The third law of thermodynamics in simple terms states that the entropy of a system at absolute zero is a well-defined constant. This is because a system at zero temperature exists in its ground state, so that its entropy is determined only by the degeneracy of the ground state.
It predicts the properties of a system and the behavior of entropy in a unique environment known as absolute temperature. The absolute temperature is the lowest temperature known and sets a lower limit to the Universe's temperature range.
The third law essentially tells us that it is impossible, by any procedure, to reach the absolute zero of temperature in a finite number of steps. Most of the direct use of the third law of thermodynamics occurs in very low temperature applications, to predict the response of various materials to temperature changes.
Answer:
The third law of thermodynamics states that the entropy of a perfect crystal at a temperature of zero Kelvin (absolute zero) is equal to zero.
