For a given mass, as radius decreases, would atmospheric pressure increase, since surface gravity would increase? I'm assuming that atmospheric composition doesn't change.
For a planet with radius = 1.1*Earth and mass = 1.3*Earth and atmospheric molar weight within 1% of Earth's, does a surface pressure of 108.75 kPa seem reasonable?
