What happened to the distance of the dots after the balloon expands?
This experiment modeled the expansion of the universe. As the balloon was inflated, the dots moved farther away from the home dot and each other. The results show that the farther away a dot is from the home dot, the faster its movement.
What will happen when you pump air into the balloon?
Gas particles exert pressure on the walls of the container in which the gas is filled. For example, when a balloon is inflated, the air inside it expands, thereby exerting pressure on the balloon walls. As a result, the size of the balloon increases.
What happens to the number of dots per unit area as the distance of the dots farther from the center?
– As the distance of dots go farther from the center, number of dots decreases.
What do the space between the dots represent?
Dot Diagrams The distance between dots on a dot diagram represents the object’s position change during that time interval. A large distance between dots indicates that the object was moving fast during that time interval. A small distance between dots means the object was moving slow during that time interval.
Why do balloons burst when inflated?
When we blow air into a balloon, it expands due to the elasticity of the rubber. But after a point, the rubber is expanded to its maximum point and cannot be stretched further. If the balloon is blown beyond this point, it will burst because there will be no space for the rubber to accommodate the air.
Why does a balloon expands when it is inflated?
Air molecules collide into the balloon with the same energy inside and outside the balloon. These molecules now collide into the balloon with more energy resulting in increased pressure. The increased pressure causes the balloon to expand.
What happens to the number of dots per unit?
Q1: What happens to the number of dots per unit area as the distance of dots go farther from the center? – Based on our graph, the distance with the highest probability of finding a dot is 5 inches. – As the distance of dots go farther from the center, number of dots decreases.
What do dots represent in your model?
The dots represent the electrons in the outer energy level (valence electrons) from the energy level models. All the other dot structures should have fewer electrons than the energy level model because the dot model only shows the outermost electrons.
How does a balloon burst?
The air in a balloon is at a higher pressure than its surroundings because the elastic tension of the balloon skin is pulling inwards. The high-pressure air that was inside the balloon is now free to expand and this creates a pressure wave that our ears hear as a bang.
What do balloons expand?
What made the balloon get bigger? It’s simply the expansion of air trapped in the bottle and the balloon. Air expands when it is heated; it spreads out and either fills a larger space or raises the pressure in a closed space.
How do you deflate a balloon in a bottle?
Pull on the bottom balloon membrane and watch what happens to the balloon inside the bottle. Let go of the balloon membrane and observe what happens to the balloon inside the bottle. You should see the balloon inflate as you pull out on the membrane and deflate as you let go of the membrane.
Why does a balloon inflate when placed in water?
The air from the bottle then moves into the balloon causing it to inflate. When the bottle is removed from the hot water, the balloon will stay inflated. This is because the air molecules in the bottle are still hot.
Why does a balloon deflate when it cools down?
When the air in the bottle cools down, the molecules of air slow down, move closer together, and take up less space. This will cause the balloon to deflate. When the bottle is placed into the pan of ice-cold water, the cold water causes the air inside the bottle to cool down.
Why do you put a balloon on top of a bottle?
By placing the balloon on top of the bottle, you trap the air inside of the bottle. This experiment is a great way to show how matter behaves when it is heated and cooled. Matter expands (gets bigger) when heated and contracts (gets smaller) when cooled.
