Does 420000 L of air have a greater or smaller mass than 420000 L of helium in a balloon?

At the same temperature and pressure, the molar volumes of gases are pretty close to equal (as long as they are at a low enough density to behave like ideal gasses). That being the case, one mole of helium weighs only about 4 grams while a mole of air weighs around 28.97 g (taking a weighted average of the components of the air) so for the same volume, the air would have more mass than the helium unless the helium was much colder or at a much higher pressure.

420000 L of air will have a greater mass than 420000 L of helium. This is because air is a mixture of gases where nitrogen and oxygen are the main components, both of which have higher molecular masses compared to helium.

Which one would compress more helium balloon or a water balloon?
A helium balloon would compress more than a water balloon because helium is a gas and can be compressed to a greater degree compared to water, which is a liquid. Helium is more compressible due to its lower density and ability to be more easily squeezed into a smaller volume compared to water.
Is Density of helium balloon is greater or less than air?
The density of a helium balloon is less than that of the surrounding air. This is why helium balloons float in the air. Helium is lighter than the nitrogen and oxygen that make up the majority of Earth's atmosphere, so it provides buoyancy for the balloon.
Why does helium balloons pop in the hot sun and what pressure is acting on it?
Helium expands in the heat, causing the gas inside the balloon to increase in pressure. As the pressure inside the balloon becomes greater than the strength of the balloon's material, it can pop. The pressure acting on the balloon is the sum of the internal pressure of the expanding helium gas and the external atmospheric pressure.
When you replace helium in a balloon with less dense hydrogen does the buoyant force on the balloon change if the balloon remains the same size?
Yes, the buoyant force on the balloon will increase when less dense hydrogen is used instead of helium. This is because hydrogen is even less dense than helium, so the overall density of the balloon-hydrogen system decreases, leading to a greater displacement of air and therefore a stronger upward buoyant force.
What is the answer for it already has helium but what is it?
The object that already has helium is most likely a helium-filled balloon. Helium is used to inflate balloons as it is lighter than air, causing the balloon to float.
What is the difference between having helium in a balloon and having air in a balloon?
Helium is lighter than air, so a balloon filled with helium will float. In contrast, air-filled balloons will sink because the density of air is greater than that of helium. Additionally, helium balloons will deflate faster than air-filled balloons due to its smaller molecular size.
Why do helium balloons float down?
Helium balloons float down due to the weight of the balloon being greater than the lift force generated by the helium inside. As the helium inside the balloon slowly leaks out over time, the lift force decreases, causing the balloon to float down.
Which has a greater buoyant force a huge lead zepplin or a small helium filled balloon?
a small helium balloon :) i think.... i dont actually know the answer i just know that a small helium balloon will be very buoyant :)
Which balloon can deflate faster?
A balloon filled with helium will likely deflate faster than a balloon filled with air because helium molecules are smaller and can escape through the balloon material more easily.
Medium balloon and small balloon filled with hellium which holds more heat?
Both the medium and small balloon filled with helium will not hold heat well because helium is a poor conductor of heat. The amount of helium in each balloon will not significantly affect its ability to hold heat.
Which gas inflates a balloon the longest carbon dioxide or helium and why?
Helium inflates a balloon the longest compared to carbon dioxide because helium is lighter than air, resulting in less escape through diffusion over time. Additionally, helium has smaller molecules than carbon dioxide, reducing the rate of molecules escaping through the rubber balloon material.
Which one would compress more helium balloon or a water balloon?
A helium balloon would compress more than a water balloon because helium is a gas and can be compressed to a greater degree compared to water, which is a liquid. Helium is more compressible due to its lower density and ability to be more easily squeezed into a smaller volume compared to water.
What happens to the atmospheric pressure acting on the balloon as the balloon rises?
due to pressure inside the balloon, will be higher because the balloon will try to get smaller and thus the balloon will ascent due to the low density of the helium inside the balloon.
Is Density of helium balloon is greater or less than air?
The density of a helium balloon is less than that of the surrounding air. This is why helium balloons float in the air. Helium is lighter than the nitrogen and oxygen that make up the majority of Earth's atmosphere, so it provides buoyancy for the balloon.
Why does helium balloons pop in the hot sun and what pressure is acting on it?
Helium expands in the heat, causing the gas inside the balloon to increase in pressure. As the pressure inside the balloon becomes greater than the strength of the balloon's material, it can pop. The pressure acting on the balloon is the sum of the internal pressure of the expanding helium gas and the external atmospheric pressure.
Why does a balloon filled with helium gas rises up in the air?
Helium is less dense than air, so when it is filled in a balloon, it creates a buoyant force that is greater than the weight of the balloon. This causes the balloon to float or rise up in the air.
Why do helium balloons rise in air?
Helium is less dense than the surrounding air, causing it to create buoyant force and rise. The upward force of the helium balloon is greater than the downward force of gravity. This makes the balloon float and rise in the air.
