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

A balloon-powered car is powered by the air released in the straw. One must blow into the straw which inflates the balloon. When you blow up the balloon‚ set your racer down‚ and let it go‚ escaping air from the balloon rushes out of the straw causing propulsion. The principle at work is Newton’s Third Law of Motion‚ which states that for every action‚ there is an equal and opposite reaction. In the case of the Balloon Powered Car‚ the action is the air rushing from the straw. The reaction is the

Balloon powered car 1 How does the balloon car demonstrate that energy is transformed from potential energy to kinetic energy? Explain When the balloon has air inside it‚ the car and the balloon have potential energy stored inside it. When the air is released the car moves forward and has kinetic energy. 2 Where is most of the energy ’lost’ in this car? There is a number of different possible reasons that energy could have been lost in our car: some of the air in the balloon may have escaped through

Maria Chriscia Y. Andres 10- SCA Title: The Balloon Powered Car Racer Background of the Study: Sir Isaac Newton developed three laws of motion in 1665 when he was only 23 years old. These laws revolutionized how science explained movement by describing how the forces acting on an object are responsible for the object’s motion. Balloon powered car racer is driven by air coming from a deflating balloon. As an alternative of using electricity‚ these cars make use of the Law of Action and

Technetium-99 Technetium-99 (Tc-99m) is used tens of millions of times annually. Approximately 85% of diagnostic procedures in nuclear medicine use this radioisotope. Making it the most common radioisotope used in diagnosis. Technetium-99 is used as a radioactive tracer and is detected in the body by gamma cameras. Technetium-99 is produced by bombarding Molybdenum with neutrons‚ producing Molybdenum-99. This then goes through a Beta decay with a half-life of 66 hours and produces Technetium. Technetium-99

Essay The Black Balloon The film “The Black Balloon” directed by Elissa Downs is a bold film about the realistic look at autism within a suburban family over a more traditional coming of age story. It looks at the complexities of family life without over-romanticizing Charlie’s autism and the affects it has on each member of the family as well as others outside of the family. The main theme of the film is that of Thomas’s coming of age and accepting that his brother will never be normal. Another

Does that mean that I need to march down the streets of different cities to tell everyone that I am one of the 99%‚ camp out for months at a time and take the charity of others‚ so that I can proclaim the fact that I am like 99% of the nation? I think not. 1% of the world controls most of the money and then the other 99% share in what is left. Between 2002 and 2007‚ the income of the 1% increased at least 10 times faster
