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.

Which one would compress more helium balloon or a water balloon?
A helium baloon. Water is incompressible, for most practical purposes.A helium baloon. Water is incompressible, for most practical purposes.A helium baloon. Water is incompressible, for most practical purposes.A helium baloon. Water is incompressible, for most practical purposes.
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 do helium balloon's float in air?
Helium balloons float in air because helium is less dense than the surrounding air. When a helium-filled balloon is released, the buoyant force acting on it, which is greater than the weight of the balloon, causes it to rise. This principle is similar to how ships float on water; the upward buoyant force allows the lighter helium to ascend through the heavier air.
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 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?
Carbon dioxide will keep a balloon inflated longer than helium will, because its molecules are much larger and therefore less able to escape through the material of which the balloon is made.On the other hand, helium is much lighter so will give a balloon greater lift while it lasts.

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.

Why does a balloon filled with helium gas rises up in the air?
helium is lighter that air so rises above the air. similar to oil rising above water.
