why do water balloons fall faster than air filled balloons?
i've always learned that air resistance was the only force that opposed gravity and that all objects fall at the same rate. So, if two balloons with congruent shapes have different densities, then shouldn't they fall at the same rates?
Yes, and because of this you'd find that the two balloons fall at the same rate in vacuum.
With the air filled balloon the air resistance force is larger compared to the gravity force than is the case with the water filled balloon.

Air Venturi A.G.E. Quiet Pellet Trap $89.94 Tired of having pellets and BBs scatter all over the house? The Quiet Pellet Trap ends that problem forever, because it's loaded with 15 lbs. of ballistic putty that captures and holds your ammo. It's great for outdoor use, too! The trap is suited to guns that produce less than 18 foot-pounds of energy at 10 meters. If you notice your ammo popping out of the trap, then it's time to remove the pellets and BBs stuck in the putty. But, that won't happen until you've shot a LOT of rounds. The frame of the trap is made of walnut-stained pine. It's 13.5"Hx12.5"W. There's a groove that accepts a target, such as the NRA official 10-meter 12-bull air rifle target. There's also a target backer so you can attach any size target you like. Includes: Pellet trap, 15 lbs. of ballistic putty, 1 target backer and 4 NRA 12-bull targets. You can purchase extra accessories below: AGE impact (ballistic) putty (5 lbs) NRA official 10-meter 12-bull air rifle targets |

World's Largest Airship Inflated for the First Time by E Green Technologies - No Sound
why does a cold, dry air mass exert a greater surface air pressure than an equally cold but more humid air mas?
Why does a cold, dry air mass exert a greater surface air pressure than an equally cold but more humid air mass?
The molecular weight of water vapor is approximately 5/8th of that of the dry air.Therefore water vapor is lighter than dry air.
A moist (humid) air is a mixture of Water vapor and dry air.So,moist air is lighter than dry air.As the surface pressure is the weight of the air column over a place,the weight and hence the atmospheric pressure exerted by dry air is more than that of the humid air.

Oh, chemical engineer here with a correction to a mis-statement “butane is lighter than air”.
Not so. Air has a molecular weight (MW) of 28.97. Generally, MW is used to gauge relative density to air (using the ideal gas law).
The natural gasses (lighter ones) are:
Methane (CH4) – MW 16.04 (lighter than air.
Ethane (C2H6) – MW 30 (>28.97 => toss up a bit heavier than air
Propane (C3H8) – MW 44 (heavier than air)
Butane (C4H10) – MW 58 (heavier than air)
Of course, in terms of flammability, one has to take into account what concentration in air is required for the gas to be flammable.
Each gas has upper and lower limits of flammability. Concentration of the gas in air below the lower limit and there's not enough to ignite, concentration of the gas in air above the upper limit and the gas is too “rich” to ignite.
Anywhere between the upper and lower limits and all bets are off.
Petroleum “products” need only be handled safely, knowing what the energy release capabilities are.
