I am not sure what you mean by 'depend' (please try and make your questions clear) but if you mean does the fact that a helium filled balloon will float (or rise) depend on gravity? Then the answer is Yes. if you were to take a helium filled balloon to the space station and release it inside, it would not rise, it would behave just the same as if you released a bunch of keys.
nope. just the heleum in the balloon
heleum
Heleum oxyde
The theory explaining planetary formation was ideated in the late 19th century. It's true that it has undergone a lot of modification since then to include what we've learned through observation and a bit of calculation. But the center of the idea is that at some point in time, gaseous components in a molecular cloud or nebulosity are pulled together and concentrate due to gravity. Then a long period of accretion sees the formation of a star and an associated planetary system. This is the nebular hypothesis. As more and more time passes, enough material "clumps together" that a gravity well forms and "gathers" all the material in the vicinity. Separate gravity wells "stake claim" to volumes of space around a central point where a star forms. Eventually, enough material gathers and gravity becomes high enough to form everything into a sphere, as planets are shaped in a ball because it is the most efficient response to that much gravity.

The vapor pressure of water at 70 degrees Celsius is approximately 23.76 kPa. To find the partial pressure of water vapor in the mixture, subtract this vapor pressure from the total pressure of 89.9 kPa. Therefore, the partial pressure of water vapor would be 89.9 kPa - 23.76 kPa = 66.14 kPa.
