(1)Â Â What do you assume theentropy S for a perfect crystal when T = 0?
(2)Â Â Is the S(0) still zeroif the crystal is not perfect? Why?
(3)Â Â How to calculate dSwhen under the constant pressure and c_p is given?
(4)Â Â How to calculate theentropy of H₂O at 500 K?
(5)Â Â How to calculate theentropy change for a chemical reaction if you can find the S foreach chemical?
(6)Â Â For anisolated thermodynamic system, dS Â³ 0. That is, dS= 0 for a reversible process and dS > 0 for an irreversibleprocess (spontaneous process).

1The third law of thermodynamics is sometimes stated asfollows regarding the properties of closed systems inthermodynamic equilibriumThe entropy of a system approaches a constant value as itstemperature approaches absolute zeroThis constant value cannot depend on any other parameterscharacterizing the closed system such as pressure or appliedmagnetic field At absolute zero zero kelvin the system must bein a state with the minimum possible See Answer
