A quantity of N molecules of an ideal gas initially occupies
volume V. The gas then expands to volume 2V. The number of
microscopic states of the gas increases in the expansion. Under
which of the following circumstances will this number increases the
most? ( i ) if the expansion is reversible and isothermal ( ii ) if
the expansion is reversible and adiabatic ( iii ) the number will
change by the same amount for both circumstances. Why ?
