Liquids are easier to pump than gases are to compress.
Because steam contains more energy than air for any given temperature and pressure.
Because the specific heat capacity of water is higher than that of air.
The difference between the specific volume of the working fluid in the turbine and pump is much greater for a Rankine cycle. For a Brayton cycle, the difference is much smaller.
