a) we would lose most of our water vapor into space.
b) the evaporating oceans would thicken the atmosphere greatly.
c) the erupting volcanoes would greatly increase the carbon dioxide greenhouse.
d) little would happen, as the earth is still the same mass and surface gravity.
e) the Earth would, like Mercury, lose all its atmospheric gases.
 
Heated temperature will greatly increase the atmospheric molecular escape velocity which will make earth's gravity harder to hold and escape to space, according to Jeans Escape: E=1/2 M(V square).
