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.

What can helium be used for?
It is lighter than air so it is used in balloons and airships (as a gas) to make them float and as a coolant (as a liquid). And also when you suck helium your voice changes and goes really high pitched and squeaky (your voice changes back to normal almost staight away).
How cold is too cold to leave a pit-bull outside?
No dog should be left outside, regardless of temperature.
Why your palm cold e put on it?
because its cold outside
Is it hot or cold outside?
Cold snowy weather is multiple things. Most temperatures below about 45 degrees feel cool/cold to us. So in order for it to snow it must be below 34 degrees (32 degrees to stick to the ground). Because it is snowing you can already infer it is cold outside. Then either a constant snowfall or flurries could be called cold snowy weather.
When can you find dew of frost outside?
when it is done raining
What will happen to those balloons if you take them outside on a cold day?
When you cool a gas at a constant presure, the volume of the gas decreases. Therefore, the balloons will slightly shrink.
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.
What do balloons have inside?
Some balloons just have air (the inflated ones used as decorations). The ones that rise in the air are filled with helium, a gas much less dense than air. The large balloons that carry people aloft are lifted by hot air, using propane burners. Hot air is also less dense than cooler air. The weather balloons that rise to great heights are filled with helium or other gases, and some inevitably pop when they expand to their limit in the upper atmosphere.
What is the difference between a helium balloon and a hot air balloon?
A helium balloon does not need energy to rise in the air. A hot air balloon needs fuel to rise in air. That is it needs heat energy to rise in air.i love Pizza squares i hope they put helium in then one dayHelium relies on the fact that helium is lighter than air. Hot air balloons rely on the fact that hot air has less volume than cold air and is lighter than the air around it. hot air balloons use hot air to cause the balloon to lift as helium balloons use a special gas to cause lift

Will a balloon deflate faster in warm or cold temperatures?
A helium balloon of the same material will deflate faster. Helium molecules are smaller than those in regular air, so they'll seep through tiny holes and imperfections in the skin of the balloon faster. When using the standard PIN analysis - both helium and common air balloons were found to deflate at the same rate. To the naked eye, both balloons stuck with a pin deflated with a pop. However, if the balloons are left intact, the helium balloon will deflate faster. This is because the helium molecules are small enough to pass through the rubber balloon, and they gradually leak out.
What causes hot air balloons to fly?
Usually only balloons that are filled with helium will float. Helium is a gas that is lighter than air, so causes the balloon to fly. Note that if you blow a balloon yourself, it will just float to the ground. There are also hot air balloons in which the air is heated by an on board heater. Hot air, being lighter than cold air, rises and lifts the balloon. When the air cools, unless it is reheated, the balloon descends.
Why is more gas needed to fill helium balloons on a cold day?
Because of the weather it is not a dependable scientific method
Why does a helium balloon collapse when taken outside into the cold?
At a colder temperature, the gas takes up less volume. Other things (especially pressure) being equal, the volume of an ideal gas is directly proportional to the absolute temperature (the temperature in Kelvin). A real gas will have a behavior similar to an ideal gas, under normal circumstances.
Is helium gas cold?
Helium gas can be hot, cold, or anything in between, just like most other substances.
How does Jacques Charles law relate to aerodynamics?
He 'flew' in helium balloons. Volume increases as temperature increases. In a hot air balloon temp increases so volume increases and some air must leave the balloon. The balloon now has lift because it weighs less than the cold air outside the balloon, just like buoyancy of a boat in water.
