Why did the balloon expand more in the presence of sugar than without it?
The bubbles they saw were tiny bubbles of carbon dioxide gas that the yeast was producing as it “ate” the sugar. As the yeast continued to react, it converted more and more sugar into carbon dioxide gas. This gas was trapped in the balloon, making it inflate as if by magic!
What will happen if you add baking soda to a balloon half filled with vinegar?
SCIENCE: When baking soda and vinegar are mixed together, it creates a gas called carbon dioxide. The gas begins to expand in the bottle and starts to inflate the balloon. The more gas that is created, the larger the balloon will inflate.
What caused the balloons to increase in size?
When gas molecules are warmed, their average kinetic energy also increases. This means they move faster and have more frequent and harder collisions inside of the balloon. When cooled, the kinetic energy of the gas molecules decreases, meaning they move more slowly and have less frequent and weaker collisions.
What caused the changes in the size and shape of inflated balloon when placed in an Erlenmeyer flask with hot water?
Therefore, the pressure inside the flask is lower than the pressure outside of the flask. This pressure differential results in the balloon getting pushed into the flask.
What happens to the size of the balloon when the temperature is increased?
In a balloon when the temperature increases, the individual gas molecules that you can’t see but that make up gases start moving really fast. When the molecules are moving fast under higher temperatures, they run into the sides of the balloon more often making the balloon bigger.
What happens to a balloon when it is cooled down?
In a balloon, cooling the gas inside would cause the circumference to decrease. If a balloon is heated up, the gas inside will expand, causing the circumference of the balloon to increase. Similarly, if the balloon is cooled down, the gas inside contracts, and causes the balloon to shrink. Short answer: Yes.
Why does the circumference of a balloon Increase?
Since the volume of the balloon is getting bigger (Vf is less thanVi) then we know that the balloon must have expanded meaning that the circumference of the balloon must also have increased. In summary: as you heat a gas, it expands. In a balloon, this expansion would increase the circumference of the balloon.
Why does a balloon expand when filled with gas?
Long answer: Because a balloon is filled with a gas instead of nothing, the gas can contract or expand due to temperature. Think of it as a class of students, who have lots of energy – they probably want to run around in a large space instead of a small space.
What happens when you take a helium balloon outside?
If you now take the balloon outside where the air temperature is, say, 20F and therefore 480R, and you wait long enough for the air (or helium or any other gas) inside the balloon to reach that same temperature, then the balloon would shrink in the same proportion.
