No, the density is too high.
The gas inside of a balloon is less dense than the air outside of it if the balloon floats. If the balloon does not float the density of the gas inside of it is equal to or more dense than that around it.
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)
Helium gas is lighter than air and hence balloons filled with helium will float in air.
balloons have carbion dioxide (vaccum) so in the world today vaccum is the best insulaters
Yes, its to do with the gas density difference of air and helium, rather than the density of gas due to temperature.
Yes, ammonia could float inside a balloon because it is a gas lighter than air. However, it is important to handle ammonia with caution due to its pungent odor and harmful properties.
gas
Sink or float... on what? - The general rule is that an object will float if it has less density than the fluid (gas or liquid) in which it is placed.
helium gas
A balloon filled with a gas that is less dense than water, such as helium or hydrogen, will float on water due to the buoyant force acting on it. The gas inside the balloon displaces an amount of water equal in weight to the balloon, causing it to 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.
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.
For a balloon to float in the air, it must be filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.
When you stick a balloon to glass, it will not float on its own. The balloon will stick to the glass due to static electricity generated when rubbing the balloon against your hair or clothes. The balloon's ability to float is determined by the gas inside the balloon and the upward force it creates, not by sticking it to a surface.
The gas inside of a balloon is less dense than the air outside of it if the balloon floats. If the balloon does not float the density of the gas inside of it is equal to or more dense than that around it.
Helium is typically pumped into balloons because it is lighter than air and gives the balloon its ability to float.
Helium which is a lighter-than-air gas, allowing the balloon to float upwards.
