It depends on what the balloon is filled with.
A balloon may float if it is filled with any gas that is less dense than air: hydrogen, helium, even pure nitrogen gas. However, the weight of the balloon will determine whether it can be lifted by the difference in density. So the most effective lifting gases are hydrogen and helium. Helium is used because it is nonflammable and noncorrosive. Early German dirigibles (zeppelins) were filled with hydrogen, and some caught fire, notably the Hindenburg in 1937.
Larger balloons can be lifted by hot air, which is less dense than cooler air. If the air cools again, it will no longer provide lift.
What else can I help you with?
Do you need helium to make a balloon float?
Yes.
If you wanted to make a balloon float in the air which gas should you use to fill the balloon?
Helium gas is lighter than air and hence balloons filled with helium will float in air.
Is Density of helium balloon is greater or less than air?
The density of a helium balloon is less than that of the surrounding air. This is why helium balloons float in the air. Helium is lighter than the nitrogen and oxygen that make up the majority of Earth's atmosphere, so it provides buoyancy for the balloon.
Is a heilum balloon a gas-liquid mixture?
No, it is a gas-solid mixture when view as a whole. It has a solid component (the balloon itself), and a gas component (the helium)
How helium particles could escape through a hole?
Black holes maximizes the gravitational pull to infinite so multiplying the gravitational pull on a helium balloon will make it float away faster because a helium balloon has a negative in which gravity pulls it down.
Can you make a balloon that float in air?
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.
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.
Used to make a balloon float?
helium gas
Do you need helium to make a balloon float?
Yes.
If you wanted to make a balloon float in the air which gas should you use to fill the balloon?
Helium gas is lighter than air and hence balloons filled with helium will float in air.
What gas are balloons filled with to make them float?
Balloons are usually filled with helium gas to make them float. Helium is lighter than air and provides the necessary lift for the balloon to float.
What gas do you use to make a balloon float?
Helium gas is commonly used to make balloons float because it is lighter than air and creates lift. The helium gas in the balloon is less dense than the surrounding air, causing the balloon to rise.
How does heilum make a balloon float?
When helium is added to a balloon, it decreases the overall density of the balloon compared to the surrounding air. This causes the balloon to float because the buoyant force exerted by the helium is greater than the force of gravity acting on the balloon. This buoyant force allows the balloon to rise in the air.
Which gas do you put in a balloon to make it float?
Usually helium, the lightest noble gas. You can make a balloon or bag float with hydrogen gas, but it is flammable. Pure nitrogen is only slightly lighter than air, so it would not lift very effectively.
What is inside the inflated balloon?
Helium goes into a balloon to make it float.
What element is used inside balloons so they float?
Helium gas is most commonly used to fill balloons to make them float. Helium is lighter than air, which causes the balloon to rise and float.
How do you make a balloon rise?
To make a balloon rise, you need to fill it with a gas that is lighter than the surrounding air, such as helium. Helium is less dense than air, so the balloon is able to float upwards due to the lifting force created by the difference in densities.
