Unformatted text preview: house gas molecules absorb cer tain wavelengths of infrared light. o lecules absorb higher energy wavelengths or a wider range of wavelengt ichigan. ht tp://www.windows.ucar.edu/ (Accessed Nov 5) o n dioxide concentrations versus global temperature, proving that the gas Global Warming Research Research Question: How do greenhouse gases heat the atmosphere? Hypothesis: Greenhouse gases trap and reflect heat, not allowing it to leave the atmosphere. MOLECULES Carbon dioxide (CO 2 ) Methane (CH 4 ) Nitrous oxide (N 2 O) Water vapor (H 2 O) Ozone (O 3 ) MOLECULES- The greenhouse gases consist of molecules that can vibrate and have dipole mo ments while other atmospheric gases, such as N 2 or O 2 , can never have dipole moments.- These gases also contain three or more atoms per molecule. CHE M ICAL PR INC IPLES The interaction of infrared light with matter is a tool for determining structural formulas. (Chemistry 1A Lecture 41)- The greenhouse gases have the potential to vibrate and create dipole mo ments. Because of this, the molecule absorbs infrared radiation and the molecule vibrates faster. The charge of the dipole mo ment interacts with specific wavelengths of the infrared spectrum. CHE M ICAL PR INC IPLES...
