What can you say about the gas inside a balloon?
The gas inside a balloon is typically lighter than air, such as helium or hydrogen, which causes the balloon to float. The pressure of the gas inside the balloon is higher than the surrounding air, which keeps the balloon inflated. Gas molecules move rapidly and bounce off the walls of the balloon, creating pressure and giving the balloon its shape.
What kind of gas is inside a weather balloon?
Contemporary weather balloons are usually filled with helium. Helium is lighter than air, and this allows the balloon to rise as this gas is lighter than air.Hydrogen would also work as it has a low density, like helium. And hydrogen is a bit cheaper than helium because it can be "made" from water. But hydrogen is flammable or even explosive, and it is generally not used for that reason.
Does helium contract in cold weather and cause a helium balloon to sink and if warmed will it rise again?
Helium will contract in cold weather, but that may not cause a balloon filled with it to sink since the air will also contract - and by about the same amount - so the relative densities of the helium and the surrounding are would remain about the same and the buoyancy of a helium filled balloon would remain
Why is the weather balloon drawn so tall and thin?
To enable the gases inside the balloon to expand which they do when the balloon reaches high altitudes. At this point the balloon becomes much larger.
If a weather balloon with 2-meter diameter at ambient temperature holds 525 grams of helium What type of electronic probe could be used to determine the pressure inside the balloon?
A digital barometer or a pressure transducer could be used to determine the pressure inside the weather balloon. These devices are capable of measuring the pressure exerted by the gas inside the balloon and can provide accurate readings.
Why hydrogen balloon rise in air?
A hydrogen balloon rises in air because the hydrogen gas inside the balloon is lighter than the surrounding air. This makes it buoyant, causing it to float upwards. The difference in density between the hydrogen gas and the air creates an upward force, lifting the balloon off the ground.
What can you say about the gas inside the balloon?
Hydrogen
Why does a hydrogen filled in balloon rise?
Hydrogen is less dense than air, so it creates a buoyant force that causes the balloon to rise. This is because the density of the hydrogen inside the balloon is lower than the surrounding air, making it lighter and causing it to float upwards.
When is the density of the air inside a hot air balloon greatest?
The density of the air inside a hot air balloon is greatest when the air inside is coolest. As the air inside the balloon is heated, it expands and becomes less dense compared to the surrounding air, causing the balloon to rise.
What uses the same principle as a hot air balloon?
A blimp or airship uses the same principle as a hot air balloon, relying on the difference in density between the air inside the balloon (or envelope) and the surrounding air to generate lift. Both rely on the concept of buoyancy to stay aloft.
What can you say about the gas inside a balloon?
The gas inside a balloon is typically lighter than air, such as helium or hydrogen, which causes the balloon to float. The pressure of the gas inside the balloon is higher than the surrounding air, which keeps the balloon inflated. Gas molecules move rapidly and bounce off the walls of the balloon, creating pressure and giving the balloon its shape.
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.
When is the density of a hot air balloon the greatest?
The density of a hot air balloon is the greatest when the air inside the balloon is at its maximum temperature. As the air inside the balloon is heated, it expands and becomes less dense compared to the surrounding air, causing the balloon to rise.

Is inside balloon solid liquid or a gas?
Inside a balloon is typically filled with a gas, such as helium or air.
What is used to power a hot air balloon?
There is the fire that changes the density of the inside of the balloon causing it to rise.
When a helium balloon rises in the air it expands If the volume of the balloon doubles what happens to the density of the helium inside it?
If the volume of the balloon doubles while the mass of helium remains the same, the density of helium inside the balloon would decrease by half. Density is calculated as mass divided by volume, so if volume doubles and mass stays the same, the density will decrease.
