The low temperature inside the freezer causes the air inside the balloon to contract.
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.
Balloons float up in the air because they are filled with a gas that is lighter than the surrounding air. This gas, often helium or hydrogen, creates a buoyant force that is greater than the force of gravity, causing the balloon to rise.
Alcohol is flammable, so putting it in a balloon could create a fire hazard. In addition, the fumes from the alcohol could expand the balloon and potentially cause it to burst. It is not safe or recommended to put alcohol in a balloon.
The balloon would get larger as the air pressure outside it dropped. At some height, the balloon would get large enough to burst.
The balloon would expand due to the lack of atmosphere on the moon, but it wouldn't burst because the pressure inside the balloon would equalize with the low pressure outside. Additionally, the balloon would float in the lower gravity environment of the moon.
It would shrink (according to Charles's Law).
Putting an air-filled balloon in a refrigerator will cause it to shrink.
The balloon would shrink because the average kinetic energy of the gas molecules in the balloon decreases when the temperate decreases. Go and try it is a pretty fun!

The balloon would shrink in size as the air inside cools and contracts. This is because gases, like the air in the balloon, contract when they are cooled and expand when they are warmed.
As it gets colder the air molecules move closer together and the balloon deflates.
the balloon's volume would decrease!!!
If the balloon is filled with water, and the water freezes, the balloon will expand and may burst. This is because at temperatures below 4ºC, water begins to expand and as it turns to ice, it has a larger volume than when it was liquid.
That would depend on whether the balloon was empty, full of air or full of water and as you have not told us which we can not help you. When asking questions please make them specific if you want us to help.

The balloon would shrink in size as the pressure increases with depth, causing the air inside to compress. If the balloon were to reach a depth of ten feet below the water surface, it would likely shrink significantly due to the increased pressure underwater.
You would think that the balloon at the lowest temperature would shrink the fastest due to the simple ideal gas law equation. PV=nRT HOWEVER the temperature is not the determining factor in this case. Hydrogen leaks through rubber and the greater the temperature the faster the leakage. So it will be the balloon at the HIGHEST temperature that will leak the fastest. This is also true for Helium. Other gases obey the Ideal Gas Law.
