Hot Air Balloon Report Hot air balloons fill up slowly and then rise in the sky. Two important principles of physics: the ideal gas law and Archimedes’ principle are the reasons hot air balloons fly. The mathematical relationship between the volume pressure and the temperature of a gas is called the ideal gas law. When a gas is heated‚ as in a hot air balloon‚ then its volume will increase. However‚ there is a heater located in the balloon’s basket that heats the air inside the balloon and blows

Most people think that when the air from a helium balloon changes your voice it is hilarious because you may sound like Donald Duck. He is a funny character and his voice is different than what we hear every day. When you take helium into your mouth and begin to talk‚ it makes you sound like Donald Duck with his high-pitched voice. You generate sound by vibrating two small flaps of mucous membrane‚ called vocal folds. Donald Duck’s vocal cords are vibrating faster than normal people’s which makes

Technology in Practice Part II: Intra-Aortic Balloon Pump Background of Technology Before tThe intra-aortic balloon pump (IABP) became a successful piece of technology‚ it was first introduced by Harken in 1958 in hopes of treating left heart failure (IABPumpers‚ 2006). Harken thought that by removing a certain amount of blood from both femoral arteries during systole‚ and rapidly replacing it during diastole‚ he could augment the cardiac output and increase coronary perfusion. However

The fire‚ now deprived of oxygen‚ can no longer burn. Make a Mini Hot Air Balloon + Air Density Learn about air density as you make a simple hot air balloon in this easy science project. In its simplest construction‚ a hot air balloon is comprised of an envelope (the balloon part)‚ a basket‚ and a fuel source. We’ll show you how to construct an envelope from a super-lightweight trash can liner and fuel your balloon with birthday candles. What You Need: * Aluminum foil (for the basket)
