all compound have many different atoms that vibrate. as u increase the temperature of the compound the atoms get more and more excited and therefore vibrate and move more vigerously. this allows them to move further apart and therefore fill a larger area. on the other hand if u cool a compound down the particles becomr less excited and take up a smaller area. the cold balloon is a perfect example of this.

∙ 13y agoThe reason party balloons shrink in cold weather is because they are inflated inside, at around 70 degrees Fahrenheit. When the air gets colder, however, the helium molecules shrink, and so do the balloons. The same thing happens with bicycle tires.

∙ 10y agoThey shrink because of Charles' Law, which describes the direct relationship between volume and temperature. As the temperature goes down (which is a measure of kinetic energy,) the volume goes down as well.

∙ 14y agoballoons shrink because eventually as time elapses the gas inside the balloon comes out of the balloon that's why the balloon shrinks.

Is cold air heavier than warm air?
False because warm air rises. The particles in cold air are moving more slowly and make cold air more dense than warm air.
What makes a balloon deflate hot water or cold water or cold water?
Cold water causes a balloon to deflate because the cold air the cold water releases is more dense than the hot air hot water releases. Take a hot air balloon for example, the flames cause the air in the balloon to heat up, causing the hot air balloon to rise. In order to make the balloon go down, you slowly turn on and off the flames in order to cool the air already inside the balloon over a period of time.All in all, cold waters causes balloons to deflate.P.S. Sorry if that made absolutely no sense, it's rather difficult explaining these types of things. c:
Why do balloons make a noise when they pop?
they make the noise because all of the air that was in there comes out so fast. _ When you pop the balloon the air comes out so fast that it's faster than the speed of sound creating a sonic boom
Does Egyptian cotton shrink?
Yes, Egyptian cotton can and does shrink. In order to avoid this, make sure you do not watch your Egyptian cotton in hot water. You also will want to allow the cotton to air dry and avoid using a drying machine.
Can same type of balloons withstand the same amount of pressure?
Yes, no matter how much air is filled inside of the balloons.
Does cold air shrink or stay the same?
No; that is why it is called shrink wrap.
Why is hydrogen used to inflate hot air balloons?
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
Do balloons deflate faster in hot or cold air?
cold air because hot blowes them up
Why does cold air shrink balls?
to Obtain Heat
When balloons are filled with this they are lighter than air?
Hot air, hydrogen or helium are lighter than cold air.
When balloons are filled with this they are lighter than air.?
Hot air, hydrogen or helium are lighter than cold air.
How do hot air balloons use air to fly?
Hot air balloons use the fact that hot air rises as a way to make balloons fly. When the air inside the balloon is heated, it rises, and this creates lift which is used to make the balloon fly.
Why does cold air have a higher density than warm air?
Yes, cold air has a higher density than hot air, and that is why hot air balloons rise, it rises above the cold air. hot air is less dense than cold air^
Does linen shrink?
Yes it can shrink. You should hand wash or use gentle cycle with cold water and air dry.
Why would a basketball shrink half its size in cold weather while in a trunk?
Cold air is dense.
Why does cold air make helium balloons collapse when you take them outside?
Cold air molecules move slowly, while hot air molecules move quickly. That's why cold air contracts, weighs less, and go down, while warm air expands, gets lighter, and go up. The cold air inside a helium balloon would contract and make the balloon collapse. Otherwise, there would be a vacuum in the balloon.
If Two balloons a and b are filled with hot air and cold air respectively how would you compare their densities?
A<b
