What else can I help you with?
Would a balloon rise in an atmosphere where the pressure was somehow the same at all altitudes Would a balloon rise in the complete absence of atmospheric pressure such as on the surface of the moon?
No
What would be the length of the arrows if the balloon were inflated more?
The length would stay the same as the pressure inside the balloon equals the atmospheric pressure.
what are the dependent and independent variables of a ballon depending on atmospheric pressure?
The mass of the balloon is independent. Atmospheric pressure will not change this because atoms are not being added or taken away from the balloon itself or its contents. The volume of the balloon will change, however, as it will expand or compress in response to the atmospheric pressure around it. The volume, therefore, is a dependent variable in this situation.
Is the pressure inside the balloon equal to the atmospheric pressure?
Think about this: if the pressure WERE equal, what would happen in the instant when you open the neck of the balloon and whatever pressure is on the inside meets the pressure that is on the outside (atmospheric pressure)? In your experience, what DOES happen?
How would you demonstrate the presence of atmospheric pressure?
Suck the air out of a container and watch it being crushed. Look at a balloon. Its round shape tells you that the pressure (atmospheric) from outside acts equally from all directions. Now take that balloon up a mountain and watch the balloon get bigger. There is less atmospheric pressure acting on the outside of the balloon the higher you go so the pressure inside the balloon makes the balloon bigger.
What would happen if you put a balloon in the sun?
It would expand as the gases inside expand against the pressure of the skin of the balloon and the atmospheric pressure.
When would less helium be needed to fill a balloon?
The lower the atmospheric pressure, the less helium is needed.
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.
What would cause a balloon to expand if taken to the top of a mountain?
Lowered Pressure
What would happen if you took an inflated balloon to the top of a mountain?
If you took an inflated balloon to the top of a mountain, the air pressure surrounding the balloon would decrease as you ascend. This would cause the air inside the balloon to expand, potentially leading to the balloon bursting if the pressure differential is too great. Additionally, the lower air pressure at higher altitudes would cause the balloon to appear larger than it would at sea level due to the decreased external pressure pushing against it.
What would cause a ballon to expand if taken to the top of a mountain?
As a balloon ascends to the top of a mountain, the atmospheric pressure decreases. This reduction in external pressure allows the air inside the balloon to expand, causing the balloon to inflate more. Additionally, the temperature may also drop, but the primary factor for expansion is the lower pressure at higher altitudes.
Is it possible for a balloon with an initial pressure of 200.0kPa to naturally expand four times its initial volume when the temperature remains constant and atmospheric pressure is 101.3kPa?
No, it is not possible for the balloon to naturally expand four times its initial volume while the temperature remains constant. According to Boyle's Law, at constant temperature, the pressure and volume of a gas are inversely proportional. Since the atmospheric pressure remains constant, the balloon's pressure of 200.0kPa would need to increase to expand, which cannot happen at constant temperature.
