invented by the Montgolfier Brothers consisted of balloons filled with hot air because they discovered that hot air cause a fabric to raise in the air‚ and it was more effective than using a gas lighter than air because the gas escaped from the balloon. • What were the differences between the balloons developed by the Montgolfiers and those developed by J.A.C Charles? • The Montgolfiers used a balloon that was filled with hot air and the balloons developed by J.A.C Charles were filled with hydrogen

HOW TO CREATE BALLOON ARCHES BUILDING AN ARCH Arches are a fun and popular balloon decoration with endless potential for creativity. From shopping malls to hotel ballrooms‚ Supplies: arches add excitement and provide lavish displays of color.

Yet it can fill over 50 balloons! How can such a small tank contain enough helium to fill so many balloons? _The tank is compressing the helium into a denser state but when it is put in the balloons it expands and takes up more space. __________________________________________________________________________ ____________

LANSA flight 508 On 24th December 1971‚ the ill-fated LANSA flight 508 hit the ground after being caught in a thunderstorm while travelling from Lima to Iquitos with a stopover in Pucallpa. Even on hitting turbulent weather‚ the flight operators decided to continue flying killing 90 out of 91 people on board‚ including 6 members of the flight crew. The lone survivor was Juliane Koepcke‚ a 17-year-old German Peruvian. The young girl was strapped on to her seat and hit

developed from the free balloon. Three classes of airships are recognized: the non-rigid‚ commonly called blimp‚ in which the form of the bag is maintained by pressure of the gas; the semi-rigid airship‚ in which‚ to maintain the form‚ gas pressure acts in conjunction with a longitudinal keel; and the rigid airship‚ or zeppelin‚ in which the form is determined by a rigid structure. Technically all three classes may be called dirigible (Latin dirigere‚ "to direct‚ to steer") balloons. Equipped with a bag

Mechanics Tutorial No. 1 2.15 A team is designing a helium-filled balloon that will fly to an altitude of 24‚000 m. As the balloon ascends‚ the upward force (buoyant force) will need to exceed the total weight. Thus‚ weight is critical. Estimate the weight (in newtons) of the helium inside the balloon. The balloon is inflated at a site where the atmospheric pressure is 0.89 bar and the temperature is 22°C. When inflated prior to launch‚ the balloon is spherical (radius 1.3 m) and the inflation pressure
