1.Why did balloons get bigger when the pump was turned on?
2.What was happening at the molecular level?
Gas notes:
-All gasses essentially behave the same.
-Gases are dense, the molecules weigh more and are spread farther apart
-Diffusion the slowness of molecules when the bump into other molecules
1. I believe that the balloons got bigger, because the amount of molecules in the "cake vacuum" was diminishing and the air within the balloons was expanding. When the pressure from the pump was released the balloons shrunk down to their regular size. Simply cause and effect. When the molecules were sucked out the balloons got bigger, and reverse when the molecules were going back in the "cake vacuum".
ReplyDelete2. The molecular level was decreasing when the pump was sucking out the molecules. When the pump was shut off the molecules were allowed to go back into the "cake vacuum" the molecular level increased.
Mr. Schultz said " gas molecules move and are far apart." "The molecules around the object shrink"
ReplyDeleteThe molecules in the balloon are moving and bounce on the outside and inside surfaces. If you take away molecules on the outside the balloon expands.
Key things air molecules move and are far apart!
