What else can I help you with?
Is rubber resistant to helium?
yes it is resistant. helium does not react with anything.
Is helium non-combustible gas?
Yes, helium is a non-combustible gas. It is chemically inert, meaning it does not easily react with other substances to ignite or burn. This property makes helium safe for use in various applications where combustion is a concern, such as in balloons or airships.
What is helium used in every day life?
-inflates balloons-as a inert gas shield for welding-protective gas in growing silicons-helps NASA shuttles get into space-makes up 0.0005% of the earths atmosphere.
Why balloons are filled with helium?
Filling a balloon with enough helium for flight takes a lot of helium, hot air balloons only use hot air because it only takes a couple of tanks of propane to heat the air, which is much more cost effective than filling the balloon with helium. Airships use helium because they are used to stay in the air for extended periods of time, so it makes sense to pay for the helium to fill it once, rather than the propane to keep the air hot.
What makes a helium balloon?
A helium balloon is made by filling a latex or mylar balloon with helium gas, which is lighter than air, causing the balloon to float. The helium gas is sealed inside the balloon, allowing it to stay afloat for a period of time before slowly deflating.
Is there helium in airships?
Yes. Helium isn't flammable, which makes it the safer option.

What gas does make a balloon float?
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.
Why don't they use hydrogen gas in airships nowadays?
Hydrogen gas is highly flammable and poses a significant safety risk. Therefore, helium gas is commonly used in airships today as it is non-flammable and safer. Additionally, helium has a higher lifting capacity compared to hydrogen, which allows for better control and stability of the airship.

What property of helim makes it good for filling balloons?
It's Helium. Helium is lighter than the air around us, so it tries to go upward. This makes the balloon float. The other gas lighter than air catches fire easily, so they don't use that. That's the basic definition. Comment if you want the technical one.
What are the differences between the properties of helium and nitrogen?
Helium and nitrogen have different properties. Helium is a noble gas that is lighter than air and does not react with other elements. Nitrogen is a non-metal gas that makes up about 78 of Earth's atmosphere and is essential for living organisms. Helium is used in balloons and as a coolant, while nitrogen is used in fertilizers and as a protective gas in food packaging.
What chemical property of helium makes it a better choice than hydrogen for use in airships?
It's very light (only hydrogen gas is less dense than helium), it's relatively cheap, and (most importantly) it's not flammable (hydrogen gas is--the Hindenburg was filled with hydrogen gas).
What makes helium float?
Helium-filled objects "float" in most substances that aren't primarily hydrogen or helium because of it's less dense. Helium has a weight of 0.1785 grams per liter. Nitrogen, on the other hand, which makes up 80% of the air we breathe, weighs 1.2506 grams per liter. Things that are lighter over the same surface area are more buoyant.However, helium isn't the lightest element. Hydrogen, weighing a mere 0.08988 grams per liter, is. The reason hydrogen isn't used as commonly as helium to fill things is because of the high flammability of hydrogen, with a small spark causing a hypothetical hydrogen balloon to explode.
