The third law of thermodynamics is concerned with the :
The correct option is C value of absolute entropy
The third law of thermodynamics is sometimes stated as
follows, regarding the properties of systems in equilibrium at absolute zero
temperature:
The entropy of a perfect crystal at absolute zero is exactly
equal to zero.
At absolute zero (zero kelvin), the system must be in a
state with the minimum possible energy, and the above statement of the third
law holds true provided that the perfect crystal has only one minimum energy
state. Entropy is related to the number of accessible microstates, and for a
system consisting of many particles, quantum mechanics indicates that there is
only one unique state (called the ground state) with minimum energy. If the
system does not have a well-defined order (if its order is glassy, for
example), then in practice there will remain some finite entropy as the system
is brought to very low temperatures as the system becomes locked into a
configuration with non-minimal energy. The constant value is called the
residual entropy of the system.
