What happens to a balloon filled with helium or CO2 when put in the Refirgarator?
When a balloon filled with helium or CO2 is placed in the refrigerator, the gas inside the balloon will contract and become denser due to the lower temperature. This will cause the balloon to deflate slightly or shrink in size. Once the balloon is removed from the refrigerator and returns to room temperature, the gas will expand again and the balloon will regain its original size.
What happens to gases when they are cooled?
The molecules of the gas will slowly start to slow down, causing a drop in temperature.
What happens to a helium balloon in heat?
In heat, the helium inside a balloon will expand, causing the balloon to inflate further and possibly burst if the heat is excessive. Heat causes the helium molecules to move more quickly and spread out, increasing the pressure inside the balloon.
Why do helium balloons shrink and stop floating?
Helium filled balloons stop floating because the helium leaks out. The balloon latex is porous and the helium is a very small atom and leaks out causing the balloon to lower and eventually stop floating.
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
How do helium balloons fall?
Helium diffuses through te balloon skin, out of the balloon, and its bouyancy therefore decreases.
What happens when a helium-filled balloon is released and rises into the atmosphere?
As the helium-filled balloon rises into the atmosphere, the surrounding air pressure decreases while the pressure inside the balloon remains the same. This causes the helium inside the balloon to expand, making the balloon increase in size. Eventually, the balloon will reach a point where the difference in pressure between the inside and outside of the balloon will be equal, and it will float at that altitude.
Why is a hellium balloon on the ceiling one day and on the floor the next?
A helium balloon rises to the ceiling because helium is lighter than air, allowing the balloon to float. Over time, helium slowly escapes through the balloon's material, causing it to lose buoyancy. Once the balloon's helium level decreases enough, it can no longer stay afloat and descends to the floor. Temperature changes and air pressure can also affect the balloon's behavior, contributing to its descent.
Why a helium weather balloon expands as it rises in the air. assume that the temperature remain constant.?
When the helium balloon starts gaining height, the pressure decreases and as the gas molecules are very freely movable (higher than the normal). They move apart from each other in the mean while they make the balloon to expand. The decrease in atmospheric pressure relative to pressure inside the balloon causes it to expand.
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 helium balloon doubles as it rises, the density of the helium inside it decreases. This is because the same amount of helium gas is now spread out over a larger volume, leading to a lower density.
What happens to a balloon filled with helium or CO2 when put in the Refirgarator?
When a balloon filled with helium or CO2 is placed in the refrigerator, the gas inside the balloon will contract and become denser due to the lower temperature. This will cause the balloon to deflate slightly or shrink in size. Once the balloon is removed from the refrigerator and returns to room temperature, the gas will expand again and the balloon will regain its original size.
What is going to happened when a balloon is filled with helium and is left in a car over night temperature drop 20 degrees?
Its volume will be reduced so it will be deflated. As long as there is no leakage, this is due to the fact that the drop in temperature reduces the kinetic energy of the gas atoms, which decreases the collisions between them and the sides of the balloon, which will cause a reduction in the pressure. As long as there is no leakage of the gas, the helium balloon will re-inflate when the temperature increases.
When a van with closed doors containing helium balloon floating on it accelerates what happens to helium balloon?
It appears to move in the opposite direction to the motion of the van
Explain why a helium weather balloon expands as it rises in the air Assume that the temperature remains constant?
When the helium balloon starts gaining height, the pressure decreases and as the gas molecules are very freely movable (higher than the normal). They move apart from each other in the mean while they make the balloon to expand. The decrease in atmospheric pressure relative to pressure inside the balloon causes it to expand.

What happens to a helium balloon in heat?
In heat, the helium inside a balloon will expand, causing the balloon to inflate further and possibly burst if the heat is excessive. Heat causes the helium molecules to move more quickly and spread out, increasing the pressure inside the balloon.
What will happen when you release a balloon filled with helium in the air?
When you release a balloon filled with helium into the air, it will rise due to the helium being less dense than the surrounding air. As it ascends higher, the air pressure decreases and the balloon expands. Eventually, the helium will escape from the balloon and it will likely deflate and fall back to the ground.
