GLOBAL WARMING AND GREEN HOUSE EFFECT – HOW CAN WE STOP THEM ? The greenhouse effect occurs when certain gases in the atmosphere trap infrared radiation whereas Global warming refers to an increase in the average temperature of the Earth as a result of the greenhouse effect. Burning fossil fuels raises the level of carbon dioxide in the atmosphere‚ and it is a major contributor to the greenhouse effect and global warming. We can help to reduce the demand for fossil fuels‚ which in turn reduces

Our Infrared Spectroscopy (IR) spectrum for our Acetaminophen KBr pellet provided a handful of strong peaks and hints that helped us to hypothesize what functional groups might be in Acetaminophen. The peaks that were at the highest wavenumbers were analyzed first. The strong peak at 3325.82 cm-1 was an indicator that there was stretching occurring between a Hydrogen and Nitrogen atom. This signified that Acetaminophen could contain an amide group. The next defined peak is located at 3162.26 cm-1

This oil was identified as eugenol by comparison of its infrared spectrum with an authentic sample. POST LAB 2.) The active component is Eugenol. It is a phenylpropene‚ an allyl chain-substituted guaiacol. Eugenol is a member of the phenylpropanoids class of chemical compounds. It is slightly soluble in water

until the IR illumination conditions of that region nearly constant. For example‚ if the potentiometer is tuned inside room/building for maximum sensitivity and then taken out in open sunlight‚ it will require retuning‚ since sun’s rays also contain Infrared (IR) frequencies‚ thus acting as a IR source (transmitter). This will disturb the receiver’s sensing capacity. Hence it needs to be returned to work perfectly in the new

among other things. By looking at the shape of the spectrum of light emitted by a star‚ we can tell something about its average surface temperature. i) If we observe a star’s spectrum and find that the peak power occurs at the border between red and infrared light‚ what is the approximate surface temperature of the star?
