It is a disordered motion.
no, the air inside balloons is a gas and therefore the particles are moving quickly and are spread out, bouncing off the sides of the balloon. Particles in solids are packed close together.
your swan ganz catheter is more inside than that required for wedge position, therefore after inflation of the balloon ,the balloon may come in the way of tip of the catheter and it will not show the tracing of the catheter.
The pressure in a container is due to the particles of the gas hitting the inside walls of the container.
Natural air is always a mixture, and more or less homogenous in its major constituents. However, if the balloon was inflated by mouth, it will have less oxygen and more carbon dioxide than the air outside the balloon, which is also a mixture.
they slow down
Helium goes into a balloon to make it float.
What keep balloon inflated is not the molecular forces but the kinetics energy of the gas molecules made the molecules to bump and create the pressure inside the balloon.
more gas particles increases the pressure inside the balloon expanding it, since gas particles hit the inside of the balloon.
An inflated balloon bursts if it is pressed hard because the molecules inside the balloon squeeze when it is pressed hard and air exerts pressure so the balloon bursts and let the air molecules escape from the balloon.
the heat caused the air inside to expand.
If you mean a hot air balloon, it is the expansion of the air caused by the propane burner. If you mean any balloon, it is the ability of the material to hold the air or gas inside which keeps it inflated.
Because as the balloon is heated, the gases on the inside of the balloon begin to expand and press out on the walls of balloon. If a balloon is refridgerated, the opposite is true: the gases on the inside of the balloon will begin to contract, causing the balloon to shrink.
It would get smaller as the air inside the ballon contracted.
The elastic contraction of the rubber in the balloon's membrane causes the pressure in the air inside an inflated balloon. When you inflate a balloon, you have to expand the latex of the balloon, which stretches when filled with air from a pressure of 760 mm Hg to as high as 840 (about 10% higher than standard atmospheric pressure). If you inflate a non-elastic mylar balloon, it takes no effort: the air inside is at the same pressure as the air outside.
As height is gained the outside air pressure on the balloon is reduced. This reduction allows the gas inside the balloon to expand.
because outside air is no longer compressing the sides of the balloon, so the pressure outwards is unbalanced and the balloon grows
The length would stay the same as the pressure inside the balloon equals the atmospheric pressure.
