They move in a straight line until they bounce into another gas molecule or hit the wall of the container, and then they rebound and continue off in another direction until they hit something else. A hot air balloon gets lift from buoyancy, which comes from the density difference between the inside and the outside, which comes from the difference in temperature. Then, if you imagine the hot air balloon is $110^{\circ} F$ with the outside air at $70^{\circ} F$, then you come up with about $180 Pa$ pressure drop from bottom to top inside the balloon.

What is scrcpy OTG mode and how does it work? Thread the loose end of your string through the straw so that the neck of the balloon is facing towards you. This easy at-home experiment is a great way to "see" science. Molds can be a flat paddle like you might cut out of cardboard, or a full machined shape, or a fluted shape which is a compromise and made typically with 4 flutes like two paddle balloon molds joined You could fill the balloon in a pool where the amount of water being drained off was being measured. Powered by SiteManager | Contact Webmaster, what is the equation for the volume of an air balloon. In which set-up did you get a positive answer? Pull your string taut and line it up with your second post. 4. circumference is diameter * pi. So for the pressure I need the pressure which of course doesn't work. How far What is the average circumference of a balloon? - Answers Remove the balloon(s) from the hot area and. And you can get a sense of just how good the approximation of negligible compressibility is by using a very deep container and seeing if the displaced volume changes with different depths.
