Balloon Launch Presentation
Transcript: Balloon Launch Kimble PM Group * Movement of molecules. E=1/2mv E= kinetic energy m= mass of energy v= velocity Lack of Sound High The Video At the bottom it is 200K. At the top it is 500K. K is in Kelvin. That means the range in Celsius would be -73 ºC to 227 ºC, Ionosphere * Bottom is 200 KM * Top is 500 KM * Temperature -73 ºC to 227 ºC * Was once part of the "Spheres" * Overlaps Thermosphere and Exosphere * 85 KM to 600 KM * Payload box with harness: 8'' x 6'' x4.25'' * Sensors and sensor module: 2 temperature, 1 humidity, 1 pressure sensor * Camera HD Contour video camera with micro SD card and USB charger. * Tuner and recorder. Thermosphere Thermosphere The Competition warm Wet Heat Our Experiment The Great Unknown Temperature greatest Humidity least Bias *Layer closest to ground * 17 kilometers (11 miles) above ground * Contains 99% of water and aerosols, 80% of mass *Temperature Fluctuates *ΤΡΟΠΟΣ*Turning*Mixing COOLER WARMER Mesosphere * Sound is a series vibrations * Frequency is the number of occurrences of a repeating event per unit * Audible Frequency is the frequency of sound audible to the human ear * Frequency is the sounds property that most determines pitch * The numerical measure of heat * The energy off the molecules Ionosphere and Exosphere Space Grant Consortium Temperature vs. Frequency Low Photons ionize gas molecules/particles, creating ions of atoms and molecules. Due to these photons colliding with gas molecules, high energy atoms shed photons of light causing the Aurora Borealis. Seeds: less than 3 oz. Camera: 5.1 oz Sensor Modules : 5.3 oz. Box and Harness: 8.3 oz Slides: less than 3 oz Recorder and Tuner: 18.7oz Film: less than 3 oz All Items =46.4 Kinetic Energy Temperature * second layer of the atmosphere * Dry and cold * top of the stratosphere is close to 31 miles up. Bottom of it though varies. *second layer *very dry *thin air Sound and Frequency Stratosphere Supplies Needed for Our Balloon Mesosphere Humidity vs. Frequency How Will this Affect our Experiment? Dense *Density *Temperature *Gases The Great Unknown Sound in the Troposphere Stratosphere * When the temperature is hotter, the molecules will move faster. * When the temperature is colder, the molecules will move slower. Lack of Sound *Extremely low density *anacoustic zone *52-300 miles * 932-3632°F the Exosphere and Ionosphere We are testing frequency through the different atmospheric layers. Pressure vs. Frequency Ions and Protons in the Thermosphere Weights * Relative Humidity is the amount of water vapor in the air compared to the amount the air can hold at a certain temperature * With more water vapor, the sound vibrations will move through the air and water. * This changes the frequency and pitch. * The pressure of air molecules in the atmosphere affects the sound vibrations that travel through it * pressure affects the molecules. Making them move closer together or farther apart. * If there is less pressure on the molecules they move apart and sound vibrations have troubles bouncing off them, so the vibrations don't move as fast or far.
