(a) from a knowledge of the partition function z, write an expression for entropy s of an ideal fd gas. 1. express your answer solely in terms of n,, average occupancy number of the sth state. (b) write a similar expression for the entropy s of a be gas. (c) what do these expression for s become in the classical limit, when n1

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
