It makes your vocal cords go to a higher pitch witch reaches the exit of you oesophagus and exits your mouth disturbing the air particles making your voice a higher pitch. when i dummy it down this is the definition. It makes your voice high pitched!
It can also make you lose consciousness and die from hypoxia (lack of oxygen) so make sure you just take a sip from the balloon.
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.
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.
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.
A helium balloon deflates over time because the helium gas inside the balloon slowly escapes through tiny pores in the balloon material. This causes the balloon to shrink and lose its buoyancy.
Helium is a lighter element compared to air, helium also has fewer molecules than air.
Helium
It appears to move in the opposite direction to the motion of the van
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.
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.
A helium balloon floats because helium gas is lighter than air. By filling a balloon with helium, the balloon also becomes lighter than air. The helium balloon floats for the same reason that objects float on water: objects less dense than water are pushed up by buoyant forces equal to the weight of water displaced by that object. What happens in water also happens in air, and the helium balloon is pushed upwards by a force equal to the weight of air it displaces.

A balloon is filled with helium. Athough, it can be a chemical and physical change. For example you can take the helium out of the balloon, but you cant put it back in it now that its already in the air.
You could put a flexible bladder (balloon) filled with helium in it. The classic answer to this old question is: Fill it full of holes.
Nothing, helium is inert.
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.
depends how big the helium balloon is and how many
It was made out of the light gas gas Helium.
