At best they can last for several weeks. While there are some isolated cases of Mylar balloons remaining inflated for several months or even years, they are the exception rather than the rule.
Helium balloons will float in rain as long as they remain intact and the helium inside them is not displaced by water. Rainwater does not significantly increase the weight of the balloon since it mostly stays on the surface and does not fill the balloon. However, if the balloon gets too heavy due to water accumulation or if it bursts from the weight, it may lose its ability to float. Overall, helium's buoyancy allows the balloon to rise above the rain.
Helium is lighter than air, so it makes the balloon float. If you let go of the balloon, it will float up into the atmosphere because of the difference in density between the helium inside the balloon and the air outside.
The object that already has helium is most likely a helium-filled balloon. Helium is used to inflate balloons as it is lighter than air, causing the balloon to float.
Yes, its to do with the gas density difference of air and helium, rather than the density of gas due to temperature.
Yes, it can. Just as helium balloon will.
Yes, a helium-filled balloon will float in the air because helium is less dense than the surrounding air. When filled with helium, the balloon experiences a buoyant force that causes it to rise and float.
Helium
Helium gas is commonly used to make balloons float. Helium is lighter than air, so filling a balloon with helium makes it buoyant and able to float.
Hydrogen is lighter than helium. So hydrogen balloon will float better than helium.
Helium is lighter than air. hence helium balloon will float in air.
Helium!
Helium which is a lighter-than-air gas, allowing the balloon to float upwards.
