What else can I help you with?
Why are weather balloons partially infated before they're released into the atmosphere?
As you rise in elevation, the pressure around you decreases. This lower pressure would cause the balloon to expand, and burst if it was inflated to much originally. By starting it off only partly filled, it will expand to a normal size and not explode.
What happens when something winds down?
When something winds down, it gradually slows down, stops, or comes to an end. Energy or activity decreases until it eventually ceases completely.
Examples of charles' Law?
Charles law states that if the temperature of a gas increases, then the volume increases (and the opposite a.k.a. temp. goes down, volume goes down). Imagine a balloon filled with helium on a cold winter day. While you are in the shop, the balloon is normal. As you step outside the balloon begins to shrivel up. This happens because of the temp. of the helium in the balloon deceases and becomes less dense, because the helium particles lose energy and become more concentrated, decreasing the volume. But when you put the balloon in a warm area, it goes back to its original size. I hope this helped you.
What happens to the shape of a helium balloon as it rises?
As the balloon rises, the air pressure outside will decrease, and the balloon skin will deform till the pressure on both sides of the skin is the same. Thus your balloon will inflate in shape, towards the spherical, which is the limiting shape for a simple balloon.
Why do balloons decrease in size after a while?
Why does a balloon go down after a few days?A balloon goes down after a few days because the helium can pass through the skin of a balloon which then reduces the size of the balloon and the balloon then slowly reaches the floor after loosing all its helium.If you need any more help visit www.wikipidia.comThey loose air somehow.
What is inside the inflated balloon?
Helium goes into a balloon to make it float.
How does air goes out of a tightly closed balloon?
It gradually leaks out. There are tiny holes in the balloon's skin.
Where does air go in a balloon?
When you inflate a balloon, the air goes inside the balloon and fills it up. The air molecules push against the walls of the balloon, causing it to expand and take on its inflated shape.
What if the heat source in a hot air balloon goes out?
what goes up, goes down!
Why inflated balloon cannot fit into your bag?
because the air inside the balloon take up the space and it will not allow the balloon to fit in bag
Inflated balloon that is taken from a heated roomto a cold outdoor?
The balloon will shrink when it goes outside. How much it shrinks will depend on the temperature difference. As temperature decreases the gas(ses) in the balloon decrease in volume causing the balloon to shrink.
How do you lower a hot air balloon?
There is a flap in the top of the balloon that you open to let the hot air out and the balloon gets lower. Or, you can just wait a little bit, the air cools down, and it goes down, all by itself!
When a balloon goes up what type of friction slows it down?
Two thing slow the balloon down. First, air friction opposes its upward movement. Second, as the balloon gets higher, the air around it gets less dense, so there's not as much force propelling the balloon upward.
Is there such thing as a balloon that never goes down and never pops?
yes its lost in space
What happens when the hot air in the balloon cools?
When the hot air in a balloon cools down, it becomes denser and contracts. This causes the volume of the balloon to decrease, resulting in a decrease in buoyancy and making the balloon start to descend. The rate of descent will depend on factors such as the rate of cooling and the weight of the balloon.
When pressure decreases dose volume increase or decrease?
Think of a balloon. Let some air out and the pressure goes down, and the balloon decreases in size.
When was The Balloon Goes Up created?
The Balloon Goes Up was created in 1942.
