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.

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.


Is pressure in a balloon less than atmospheric pressure?

Yes, the pressure inside a balloon is typically slightly higher than atmospheric pressure to keep the balloon inflated. When a balloon is fully inflated, the pressure inside the balloon is balanced by the tension in the balloon's material, which allows it to maintain its shape.


Why does a partially inflated balloon expand as it rises?

As the balloon rises, the air pressure outside the balloon decreases while the air pressure inside the balloon stays the same. This causes the balloon to expand because the higher pressure inside the balloon pushes against the lower pressure outside.


Why does a balloon pop as it goes up to the sky?

the pressure has increased


What is the pressure inside the balloon?

The pressure inside a balloon is typically slightly higher than atmospheric pressure due to the air or gas filling the balloon creating a force against the balloon walls. The pressure varies depending on factors such as the amount of air or gas inside the balloon and the elasticity of the balloon material.


What is the pressure in a 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.


What causes the pressure in a balloon?

The pressure in a balloon is caused by the molecules of the gas inside the balloon colliding with the walls of the balloon. As the molecules collide, they exert a force on the walls, creating pressure. Additionally, the temperature of the gas inside the balloon can also affect the pressure.


What happen to the pressure in the balloon when it is inflated?

When a balloon is inflated, the pressure inside the balloon increases. This is because as the balloon expands, the air molecules become more tightly packed together, increasing the pressure. The pressure remains higher inside the balloon until the balloon is stretched to its maximum capacity.


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.


As a balloon rises does the presure inside the bag of balloon increases or decreases?

As a balloon rises, the pressure inside the balloon decreases. This is because the atmospheric pressure outside the balloon decreases with altitude, causing the balloon to expand as the pressure inside remains relatively constant.


Why does a balloon collapses when air is removed out of it?

A balloon collapses when air is removed because the air pressure inside the balloon becomes lower than the air pressure outside the balloon. This pressure difference causes the balloon to shrink and collapse.
