Presentation Transcript

  1. SankaWijesinghe, Yuki Choi, Natsumi Oka Emissions of Methane

  2. Chemistry Aspect • light energy (from the sun) penetrates the atmosphere, gets absorbed by the earth and at the same time converted to heat energy that gets absorbed by the planet’s surface. • Greenhouse gases in the Earth’s atmosphere absorbs infrared radiation. • Insulation

  3. Methane and Other Greenhouse Gases • Tetrahedral Shape • Colorless and Transparent • Greenhouse gases naturally blanket around the earth and keeps the earth warm about 33 degrees Celsius warmer • Traps 20 times more heat than carbon dioxide

  4. Physics Aspect • -Earth's average temperature is 16 degrees<--> 34 degrees higher than the Moon's average temperature. • -Atmosphere composition: 71% nitrogen, 21% oxygen, 1% greenhouse gases. • -Greenhouse gases include: water vapor, nitrous oxide, methane, and carbon dioxide.

  5. Physics Aspect (continued) • -Each gas has its own natural frequency (resonance)-->Wave lengths match the frequency. • -The majority of the radiations are penetrated to the Earth. • -Resonance + Dipole moment = Re-radiation (*Dipole moment= the measure of polarity in a covalent bond)

  6. IR Spectrum of Methane and Carbon Dioxide

  7. Self-Reflection • Communication • Lab • Organization • Deadlines • Technical difficulties

  8. Lab Results

  9. Lab 2 Results
