What is the formula you use to find the cubic feet of helium in a balloon at a given atmostpheric pressure say if it had 1 cubic feet at 1atmostpheric pressure then taken to 2 atmospheres of pressure?

Use the combined gas law PV over T = PV over T or boyle's law PV=PV where P is pressure in atmospheres and V is in liters and T is in Kelvin. The answer to your question is 1/2 cubic foot. If you double the pressure you have half the volume. Its pretty simple.

What is the pressure in a 0.34 L balloon if the temperature is 35C and the balloon contains 0.0233 mol of an ideal gas?
the pressure is 1.73289 ATM (atmospheres)
A helium-filled balloon occupies a volume of 15 cubic meters at sea level The balloon is released and raises to a point in the atmosphere where the pressure is 75 ATM What is its volume if the te?
75 atmospheres of pressure is 1125 pounds per square inch. A balloon would be unlikely to withstand this pressure.
What has to happen for a balloon to inflate?
The pressure inside the balloon has to exceed the pressure outside the balloon.
Why does a balloon pop as it goes up to the sky?
the pressure has increased
Is pressure in a balloon less than atmospheric pressure?
No, the pressure of the balloon is more than the atmospheric pressure because the gasses in the balloon are compressed by the stretched material.
How does a balloon expand?
when you fill a balloon with air the air makes pressure. the air pressure maximizes the balloon fabric allowing the balloon to expand.
What happens to a balloon when pressure becomes less?
When the internal pressure in a balloon falls, the balloon get smaller and less buoyant.
Why does the pressure outside the balloon decrease as it rises?
The pressure outside the balloon doesn't change when the balloon rises. By a balloon rising, I assume that air is being placed into the balloon. As the balloon fills with air, the pressure inside the balloon will increase. Since the balloon can stretch, the increasing pressure against its inner walls will cause it to rise, or more correctly put, expand. Eventually, the balloon will be stretched to its fullest capacity if more air is placed inside it. When it pops, the bang you hear is the high pressure of the atmosphere inside the balloon equalizing with the lower pressure of the atmosphere outside the balloon.
What is the pressure inside the balloon?
It is the pressure exerted by the elastic balloon envelope and will be higher than the external pressure.
What makes a balloon rise on air?
A balloon rises on the principle of buoyancy. This occurs when the net pressure on the bottom of the balloon exceeds the net pressure on top of the balloon.
Why does a partially inflated balloon expand as it rises?
The pressure in the balloon stays the same, but the pressure outside drops as the altitude increases. And as the outside pressure drops, the balloon expands.
Why would a balloon inside a bell jar inflate when pressure is decreased within the jar?
The balloon exists in a separate pressure system from the bell jar itself.As the balloon is open to the surrounding air, the pressure within the balloon is 1 atm (1 atmospheric unit of pressure = 105 Pa).When pressure is decreased within the jar, the pressure within the jar decreases to a value lower than 1 atm. Therefore, to counter the low pressure created in the jar, the atmospheric air moves into the balloon and pushes the balloon into the jar to attempt to equalize the pressure in the balloon and in the jar. Therefore the balloon inflates.
