Any gas that is more dense than air.
Answer:
It is a bit more complex than that - an air filled balloon would still fall because air has the density of air. In a normal inflated balloon the air in the balloon is compressed and has a density more than uncompressed air. If the "balloon" were a plastic bag wiith no air pressure above the pressure of the surrounding air, the balloon would still fall as the combined (average) density of the balloon/bag system is greater than the surrounding air. Even if the balloon were filled with a gas with a lower specific gravity than air the balloon wll fall if the compressed gas density excedes that of the surrounding air or if the combined (average) density of the balloon/bag or balloon system is greater than the surrounding air.

Why does wet helium balloons fall?
Helium filled balloons eventually fall because the helium molecules escape from the envelope of the balloon, both at the neck of the balloon and through the material of the balloon itself. The same occurs with air-filled balloons but air-filled balloons do not float to begin with -- they fall to the ground no matter how much air you put in them. In order to float, the gas within the balloon must be lighter (less dense) than the gas outwith the balloon. Inflating a balloon with the same density of gas that surrounds it will not make it float upward because the weight of the balloon alone will make it fall under gravity. Moreover, the elasticity of the balloon compresses the gas within, making it much denser, and therefore heavier.
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.
What is inside the inflated balloon?
Helium goes into a balloon to make it float.
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 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.
What would heating the gas in an air balloon make the balloon rise?
Simple...hot air rises..

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)
Why would heating the gas inan air balloon make the balloon rise?
because as you heat the gas, you cause the gas to expand on the container (whish is a balloon), this lowers the density, and a less dense fluid submersed in a denser fluid will rise, like an air bubble rises from underwater
What is inside the inflated balloon?
Helium goes into a balloon to make it float.
What gas can make a balloon float Is it hydrogen or Nitrogen or Argon or Chlorine?
Hydrogen can make a balloon float. Nitrogen, argon, and chlorine will not. However, hydrogen is combustible and in a balloon that cam near an ignition source, could produce a fire or explosion. The preferred gas for balloons, if cost is not an issue, is helium, which does not burn and is still very light.
Why would heating the gas in a hot air balloon make the balloon rise?
When the gas (air) in a hot air balloon is heated it becomes less dense. This makes the balloon more buoyant so it rises.Because heating the air inside the balloon makes it less dense than the air surrounding the outside of the balloon, so it will rise.
Why would cooling the gas in an air balloon make the balloon contract?
== == According to Charles's Law, "At constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its temperature (in Kelvin) increases or decreases." Therefore, if the temperature of the gas is decreased, the volume of the gas will decrease proportionally, and the balloon will contract.
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.
Used to make a balloon float?
helium gas
What will happen to a gas balloon if you put it on the moon?
A gas balloon would likely expand and rupture on the moon due to the lack of atmosphere and low pressure. The lack of buoyant force and the extreme conditions would cause the gas inside the balloon to rapidly expand, leading to its failure.
