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.

What can you say about the gas inside a balloon?
The gas inside of a balloon is less dense than the air outside of it if the balloon floats. If the balloon does not float the density of the gas inside of it is equal to or more dense than that around it.
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.
Does the gas inside a balloon affects its size and shape?
Yes, the gas inside a balloon affects its size and shape. When the balloon is inflated with gas, it expands and takes on a specific shape dictated by the pressure of the gas and the elasticity of the balloon material. Changing the amount of gas or pressure inside the balloon can alter its size and shape.
How you know gas is inside the balloon?
If there were nothing inside the balloon - a vacuum - the balloon would quickly collapse due to the pressure of the atmosphere outside it. A firmer structure might resist the air pressure, but not a balloon.
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 does a partially inflated weather balloon expand as it rises?
As the weather balloon rises in altitude, the air pressure around it decreases while the pressure inside the balloon remains relatively constant. This pressure difference causes the gas inside the balloon to expand, increasing its volume and size.
If a balloon is squeezed what happens to the gas inside?
When a balloon is squeezed, the volume of the balloon decreases. This causes the gas inside the balloon to be compressed, increasing the pressure of the gas.
Is inside balloon solid liquid or a gas?
Inside a balloon there is gas. This gas is normally helium if you want the balloon to fly high, but hydrogen also works.
What is inside the inflated balloon?
Helium goes into a balloon to make it float.
What can you say about the gas inside a balloon?
The gas inside of a balloon is less dense than the air outside of it if the balloon floats. If the balloon does not float the density of the gas inside of it is equal to or more dense than that around it.
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.

Changing the amount of gas or pressure inside the balloon can alter its size and shape.
What determines if a balloon filled with a gas will rise or sink in the air?
A balloon filled with a gas will rise or sink depending on the density of the gas inside compared to the surrounding air. If the gas inside is less dense than the surrounding air, the balloon will rise. If the gas inside is more dense, the balloon will sink.
Is inside a balloon a solid?
No, the inside is a gas (air).
What factors do you think are affecting the gas inside the hot air balloon?
The factors affecting the gas inside the hot air balloon are temperature, pressure, and volume. When the air inside the balloon is heated, it expands, causing the balloon to rise. Conversely, when the air cools, the balloon descends. The pressure of the gas inside the balloon also plays a role in its movement, as changes in pressure can affect the buoyancy of the balloon. Additionally, the volume of the gas inside the balloon can change as the temperature and pressure fluctuate, impacting the balloon's altitude.
The shape and the size of a toy balloons depend on the kind of gas inside?
Yes, the shape and size of a toy balloon depend on the type of gas inside. Helium makes balloons float, while air or carbon dioxide results in balloons sinking. The gas affects the overall buoyancy and volume of the balloon.
