By filling the balloon with a solid piece of carbon dioxide (dry ice) that measured 2cm^3. The solid carbon dioxide sublimated, that means that the solid disperses into gas which causes the balloon to inflate. Our balloon measured 15cm so we did the math and got a 421.75 ratio. By doing this we found out that in the molecular level the molecules moves rapidly around and bounce off of each other in the CO2. The balloon inflated because the molecules moving around creating pressure. I really enjoyed this experiment because it was fun as well as engaging. we did lots of tests, like putting the dry ice in water to see the smoke it creates. we also put a penny on the dry ice and it made the penny "scream" which i still don't know why it did that, but it would be cool to know how that works. also just playing with dry ice was fun. |
