A mixture of oxygen, nitrogen, carbon dioxide and other various gases. The only reason is floats is because the hot gas inside the balloon is lifting it up.
It's a gas. The air molecules are free to move around anywhere in the balloon.
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 gas is lighter than air and hence balloons filled with helium will float in air.
A ballon inflates when you add helium to it for the same reason that it would inflate if you added any other gas. By Boyle's law, increasing the number of atoms of a gas to a constant space must increase the pressure of that gas. That pressure, in a balloon, must balance the force required to stretch the balloon as well as the pressure of the atmosphere pressing in on the balloon. This is not the same as the density of the displaced air. The inflated balloon would have less mass than the volume of air it displaces. This would cause the balloon to be lighter than air, and thus rise. If the elasticity of the balloon were smaller than normal, it would require more helium in a smaller volume. If the elasticity was sufficiently small, the balloon would not be lighter than air.
The reaction of blowing up a balloon involves the expansion of air, which can be described using the ideal gas law: ( PV = nRT ). Here, ( P ) represents the pressure of the air inside the balloon, ( V ) is the volume of the balloon, ( n ) is the number of moles of air, ( R ) is the ideal gas constant, and ( T ) is the temperature in Kelvin. As air is blown into the balloon, the volume increases, leading to changes in pressure and temperature within the balloon.
The pressure inside a balloon is determined by factors such as the amount of air or gas in the balloon, the volume of the balloon, and the temperature of the air or gas inside. As more air or gas is added to the balloon, the pressure will increase. Conversely, if air or gas is released from the balloon, the pressure will decrease.
It's a gas. The air molecules are free to move around anywhere in the balloon.
The gas in the balloon is lighter than air. It has a specific gravity relative to air of less tha one.
A balloon filled with a gas will rise or sink depending on the density of the gas inside compared to the surrounding air. If the gas inside is less dense than the surrounding air, the balloon will rise. If the gas inside is more dense, the balloon will sink.
Only a hot mixture of the same gases that are in the air you breathe.
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.
Because the air is coming inside the balloon.
A balloon gets bigger when it is filled with air or gas because the molecules of air or gas inside the balloon move around and take up more space, causing the balloon to expand. The pressure from the air or gas inside the balloon pushes against the walls of the balloon, causing it to stretch and increase in size.
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.
The solid would be the basket and balloon, and the tanks holding flammable gas. The liquid is water vapor released by burning the gas. The gases are the fuel in the tank, and the heated air in the balloon that causes it to rise.
The factors affecting the gas inside the hot air balloon are temperature, pressure, and volume. When the air inside the balloon is heated, it expands, causing the balloon to rise. Conversely, when the air cools, the balloon descends. The pressure of the gas inside the balloon also plays a role in its movement, as changes in pressure can affect the buoyancy of the balloon. Additionally, the volume of the gas inside the balloon can change as the temperature and pressure fluctuate, impacting the balloon's altitude.
No. A hot air balloon is a solid object. That is, the basket, the ropes, the burner and the envelope itself are not gasses. The air within the envelope is a gas, of course; heated atmospheric gasses in fact. But the balloon itself is not a gas.
