As the altitude increases does air pressure increase or decrease?
decrease as if you go deep into the earth the pressure increases If you blow a balloon up at sea level, and take it up to the top of the largest mountain, if the balloon hasn't pop, it would be bigger there than at sea level, because there is less air pressure as you increase your altitude, so the air within the balloon was "compacted" more or less at sea level and brought to a altitude where air was thinner and the air within the balloon would expand to try to compensate for the difference in pressure.
A blown up balloon is carried up a high mountain will it get bigger or smaller explain why its volume changes?
As balloons increase in altitude, there is less atmospheric pressure pushing on it, so the result is that the balloon expands. The opposite is true, if you sink a balloon in water there is more pressure on the outside of the balloon so it shrinks.
A balloon is weighted so that it is barely able to float in water. What will happen if it is pushed beneath the surface?
It sinks. By pressing it under the water, the water pressure on the balloon increases slightly and compresses the air in the balloon. This increases the density of the (balloon, weight) combo so that is more dense than water, hence it sinks. High altitude weather balloons are only inflated partway with helium when they are launched from the ground. The envelope of the balloon expands as it rises in the atmosphere.
What explains why a balloon bulges on one end when you pinch the other end?
The first part of the explanation is understanding why a balloon changes when you put air into it. Before you blow up a balloon, you can see that the volume is small and that the balloon is elastic. As you put more air into the balloon you are increasing the pressure. The air is packed in tight, so it attempts to push out and escape, so the balloon's surface stretches until a balance is reached. The tension of the balloon's surface combined with the outside atmosphere's pressure matches the internal pressure of the air. This equilibrium is always held. If you increase the pressure (putting more air into the balloon) the balloon's surface gives just enough so that you equilibrium is reached again. It is this maintaining of equilibrium that answers your question. If you try and decrease the volume in one area of the balloon, the air is going to push out another area of the balloon to make up for the lost volume. The volume is always maintained and the pressure remains constant.
If a balloon is squeezed what happens to the pressure of the gas inside the balloon?
If a balloon is squeezed, then that means the volume is decreasing. Volume and pressure vary indirectly, which means that when one goes up, the other goes down. So when you are decreasing the volume of the balloon, the pressure inside is going up (assuming constant mass and temperature).
When the balloon is floating high above the ground how could the balloonist make the balloon descend gradually?
the balloonist would turn off the burner, allowing the air inside the balloon to cool down. Hot air rises so as the air cools down the balloon will lose altitude.
What might cause a balloon blown up at low altitude to burst if it is taken to a higher altitude?
at altitude the balloon's external air pressure has been greatly reduced, often expanding the balloon to the bursting point.
How would you describe the balloon when it is floating in the centre of the room?
floating front and center? (i think)
A balloon rises at a rate of 2km hr what it velocity?
That's the velocity.
What measures cloud altitude and direction?
a weather balloon
Why do most balloons burst as they ascend high altitude?
The internal pressure of the gasses inside a balloon remains constant while external air pressure decreases as the balloon ascends. As the balance between the two changes, the pressure inside becomes progressively greater than the pressure outside, so the balloon expands. If it expands beyond the ability of the balloon material to contain it, the balloon will burst.
What is the gas in the balloons used for?
to keep the balloon floating
When balloon ascends its velocity decreases?
no it increases
How does the altitude effect the size of a balloon?
As the external pressure drops with increasing altitude, balloons generally expand with height.
What happens to the hot air balloon when it reaches an altitude of 10000 meters?
the air pressure outside of the balloon decreases.
Would there be more air pressure in a balloon at sea level or high in the sky?
provided the balloon has not reached its elastic limit (it has burst!), the air pressure inside and outside will essentially be equal. [The pressure inside will be slightly less, which is where the lift comes from.] But even at altitude, the pressure will be approximately equal in and out, for at altitude, the balloon will have swelled, thus reducing the internal pressure. It will eventually reach an altitude at which the internal pressure and the external pressure will be equal, and the balloon will have reached maximum expansion. Filled at sea level, a balloon will seem empty and floppy, and very tall and thin. At altitude the balloon will fill out as the external pressure reduces.
What would happen if a balloon that was blown up at a low altitude is brought to a high altitude?
The ballon will most likely pop. The balloon will shrink.
