Block Mrs. Sneed 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

I walked out of the plane and I saw the aerodrome of Greece. It was the early phase of World war II and I was recruited as a Junior Pilot Officer‚ one below a Corporal‚ in the Royal Air force of the British Imperial Army. The runway was just a little strip of flat land surrounded with wild grass and flowers blossoming blue and yellow and red in their millions around me bordered by brown craggy mountains with a sea at a distance. It was springtime here and a gentle breeze was flowing from the sea

heavier than oxygen. As it "pours" out of the bottle‚ it pushes the lighter oxygen away from the candle. 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

Elesiya‚ to further support your interest in art and fine motor skills‚ I provided you with a hot glue gun activity. I was very impressed by your creativity and concentration throughout this learning experience. I could tell you had hot glue gun experience before because you were aware of the safety of using hot glue gun like putting gloves on and resting the glungun on the chopping board. After you put gloves on‚ you started to glue different decorations on the egg carton. You seemed to be particularly

A beauty that most people are unaware of‚ for when they repulsively recede from the heat‚ they do so from that beauty as well. He looked up at the spotlessly azure sky‚ one of the beauties on a hot day‚ and was conscious of his widening

REVIEW OF RELATED LITERATURE Introduction Balloon powered car racers are driven by air coming from a deflating balloon. Instead of using electricity‚ these cars make use of the Law of Action and Reaction. The car is propelled forward‚ as a result of the air coming from an inflated balloon. As a reaction to the force produced by the escaping air‚ a force acts towards the opposite direction thereby pushing the car racer forward. Although balloon powered car racers have been around for quite

framework for quantifying their harms. According to Nutt‚ in order to minimize these harms of drugs‚ public perception and policies must be informed by logical evidence and less determined by human ideology. His work‚ especially his book‚ Drugs without Hot Air‚ equips the reader with necessary knowledge of how drugs affect the body mentally and physically and how addiction happens. Nutt’s work contains very fascinating insight into the history of drug
