Noble gasses Firstly‚ helium has very many uses both commercially‚ recreationally‚ and in scientific research. Helium is used in both blimps and balloons because it’s much less dense than typical atmosphere. However‚ unlike hydrogen‚ helium is inflammable and therefore makes airship travel much safer‚ preventing huge loss of life like that in the Hindenburg incident. Another way helium is used for the preservation of life is in diving. Inhaled nitrogen can be very dangerous and even fatal to divers

The invention of the balloon was a very unique idea that triggered the technological ear on a race to change the face of the future of flights. The invention shifted mobility towards a faster level and it also gave a good advantage in the war. Since history people have been finding ways to fly and balloon was the first technology that ever took off in the air. Scientist in the past has put a lot of studies to make this invention possible and it gave birth to a new flight technology. A French

What? And How? 1. How is lightning formed? Cumulonimbus clouds must become electrically charged therefore‚ in most rain clouds the bottom of the rain cloud is negatively charged and the top is positively charged. Lightning is created as a discharge of built up energy due to the separation of positive and negative charges which are generated inside the thunderstorm. 2. How are tornadoes formed? Tornadoes form in unusually violent thunderstorms when there is sufficient instability‚ and wind shear

Throughout the experiments the size of the balloons stayed about the same size except for in experiment 3. Also the bottles that had more sugar had a stronger scent of alcohol and also contained more foam on top of the liquid. All yeast in each of the bottles seemed to have fermented at the same time and stopped/slowed down‚ the growing process‚ at the same time. Bottle 3 also would always overflow and the foam would fill the ballon in every experiment. Another trend with bottle 3 was that in the

Not an inflated one‚ but a new one that you just bought from a store. This deflated balloon is still so small that I cannot appreciate its beauty as a balloon. So I put more air in it and it grows to a considerable size. Imagine that the balloon is the economy‚ and the air inside it is the money circulating in the economy. If we put

But‚ what’s circulating in air among people of UK is about the miserable “Wet Summers”; that we have face.

Cameron Balloons is the world ’s largest manufacturer of hot-air balloons. (http://www.cameronballoons.co.uk) On average‚ their factory in the United Kingdom builds one balloon a day but together with their United States factory the company produces on average more than one balloon per day‚ everyday of the year. And in 1996 the company turnover was almost £7‚000‚000. (http://www.bized.co.uk) From the operations manager ’s point of view‚ inventories are a tool which provide efficient operation
