Question

Because of its very weak intermolecular attractions, at absolute zero, helium can remain a liquid. Is the entropy of He(l) at absolute zero equal to 0 J/K?
A.Yes, according to the third law, all substances have a zero entropy at absolute zero
B.Yes, liquids have fewer microstates than solids so He(l) will have a zero entropy at absolute zero
C.No, liquids have more microstates than solids. Even at absolute zero He(l) could have more than one microstate because it isn’t a perfect crystal.
D. It isn’t possible to determine the entropy of a substance at absolute zero

Explanation / Answer

Ans : C) No , liquids have more microstates than solids . Even at absolute zero He (l) could have more than one microstate because it isn't a perfect crystal

entropy is the degree of randomness or disorderness of the system . And the gases tend to have higher entropy than liquids , and liquids will have higher entropy than solids due to their packing arrangements.

So even if it is an absolute zero , the helium (l) will not have entropy of 0 J/K.
