Yes - the latter is more dense by a factor of 8 (2^3) and thus has less lifting power. To take an actual real example: Air has a weight of 1.222 kilograms/m^3

Yes - the latter is more dense by a factor of 8 (2^3) and thus has less lifting power.
To take an actual real example:
Air has a weight of 1.222 kilograms/m^3 (dry, clean, standard pressure)
Helium has a weight of about 0.167 kg/m^3.
That means that 1m^3 of helium lifts about 1kg. If you now compress that helium by a factor of 10, then 1m^3 of compressed helium would weigh 1.67kg - more than the sourrounding air and provide negative lift.
edit: get your unit and orders of magnitude right. :sigh:
