As a balloon is often inflated by blowing air into it from the mouth, the air is a mixture of atmospheric air, including the carbon dioxide from the lungs. Even if inflated using a pump, the air is still not a pure substance, as atmospheric air is a mixture of several gases.

Is helium inside a balloon a compound?
No, helium inside a balloon is not a compound. Helium is a chemical element and is the second lightest element on the periodic table. It exists as individual helium atoms inside the balloon.
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.
What happens to a helium balloon in heat?
In heat, the helium inside a balloon will expand, causing the balloon to inflate further and possibly burst if the heat is excessive. Heat causes the helium molecules to move more quickly and spread out, increasing the pressure inside the balloon.
Why does Helium pump up a balloon?
Helium is lighter than air, so when it is pumped into a balloon, it displaces the heavier air inside the balloon. This creates a lower density gas mixture inside the balloon, causing it to rise and float in the air.
Does helium contract in cold weather and cause a helium balloon to sink and if warmed will it rise again?
Helium will contract in cold weather, but that may not cause a balloon filled with it to sink since the air will also contract - and by about the same amount - so the relative densities of the helium and the surrounding are would remain about the same and the buoyancy of a helium filled balloon would remain
Is the air inside a balloon a pure substance?
In a helium balloon- one that floats and rises to the ceiling it is elemental helium that is used to inflate the balloon. If you just blow into a balloon to inflate it then it is air inside the balloon which is a mixture of gases, principally nitrogen and oxygen (both elements). There are also other gases that are chemical compounds such as carbon dioxide.
What gas is inside an air balloon?
Helium is usually the gas inside an air balloon. It is lighter than air and helps the balloon float.
Is air inside a balloon a element?
In a helium balloon- one that floats and rises to the ceiling it is elemental helium that is used to inflate the balloon.

There are also other gases that are chemical compounds such as carbon dioxide.
What is inside the inflated balloon?
Inside an inflated balloon is typically air or another gas, such as helium. The gas inside the balloon causes it to expand and creates the balloon's buoyancy.
Does a helium balloon float with anything inside?
Helium

Is inside balloon solid liquid or a gas?
Inside a balloon is typically filled with a gas, such as helium or air.
How much can a helium balloon lift?
The lifting power of a helium balloon depends on its size and the amount of helium inside. On average, a standard 12-inch helium balloon can lift about 14 grams.
What happens when a helium-filled balloon is released and rises into the atmosphere?
As the helium-filled balloon rises into the atmosphere, the surrounding air pressure decreases while the pressure inside the balloon remains the same. This causes the helium inside the balloon to expand, making the balloon increase in size. Eventually, the balloon will reach a point where the difference in pressure between the inside and outside of the balloon will be equal, and it will float at that altitude.
Why does Helium pump up a balloon?
Helium is lighter than air, so when it is pumped into a balloon, it displaces the heavier air inside the balloon. This creates a lower density gas mixture inside the balloon, causing it to rise and float in the air.
