and warms the earth. Most of this light reaches the earth’s surface as short-wave radiation. When short wave radiation from the sun hits the earth’s surface it changes to long-wave infrared radiation‚ which bounces back into to space ("National Geographic"). However‚ there is a certain percentage of long-wave infrared radiation trapped by greenhouse gases in the atmosphere. On absorption and subsequent reflection of long-wave radiation to the surface of the earth‚ more heat is conserved on the surface

Global Warming: Origins‚ Effects‚ and Potential Solutions Since the dawn of the 19th century‚ civilization has been very dependent on the consumption of fossil fuels. Greenhouse gases‚ especially carbon dioxide‚ coming from these emissions plague our atmosphere. Greenhouse gases trap heat and prevent warmer air from escaping our atmosphere‚ which causes a containment of excess heat‚ thus causing a climate change; in this case‚ a rise in temperature. There has been large amounts of debate on whom

(FIGURE-4) In order to tell how much borneol is formed during reactions‚ both qualitatively and quantitatively‚ infrared spectroscopy and gas chromatography are executed on the products formed from Sodium Borohydride Reduction and Meerwein-Ponndorf-Verley Reduction (MPV). Infrared (IR) spectroscopy shows the relative absorption of specific chemical bonds in a molecule to the induced infrared radioactive energy. Thus from looking at the peaks on IR spectrum‚ possible functional groups in a compound

2D1426 Robotics and Autonomous Systems Project Report Group 5: “Ad Hoc”. Frontal view of the vicious “Ad Hoc” robot Team members: Heijkenskjöld‚ Hannes Kalén‚ Martin Malmesjö‚ Stefan Hoc‚ Ad Abstract This is a report of the project for the course 2D1426 Robotics and Autonomous Systems. It describes the ideas and the design of the Ad Hoc robot. It covers the main design goals‚ implementation and results. The goal of the robot was to play table hockey‚ and above all to be able to

Identification of Unknown Organic Compounds by Melting Point‚ Boiling Point‚ and Infrared Spectroscopy Methods and Background The goal of this laboratory experiment was to determine the structure and identity of an unknown solid and an unknown liquid by using elemental analysis‚ index of hydrogen deficiency‚ infrared spectroscopy‚ melting point (for solid)‚ and boiling point (for liquid). In this laboratory‚ we were given unknown solid “C” and unknown liquid “D”. The empirical formula

Conduction Conduction Conduction is the transfer of thermal energy between regions of matter due to a temperature gradient. In the engineering sciences‚ heat transfer includes the processes of thermal radiation‚ convection‚ and sometimes mass transfer and often more than one of these processes occurs in a given situation.Shaun Prado 8F Shaun Prado 8F Steady-state conduction Steady state conduction is the form of conduction.

pollution. Earth’s atmosphere contains mostly water vapor‚ carbon dioxide‚ and methane (natural greenhouse gases) which act to keep the lower layers of the atmosphere warmer than they otherwise would be without those gases. Greenhouse gases trap infrared radiation. The radiant heat energy that the Earth naturally emits to outer space in response to solar heating. Mankind’s burning of fossil fuels releases carbon dioxide into the atmosphere and this is believed to be enhancing the Earth’s natural

shape of the crystals will differ for each specific drug. 5. What is spectrophotometry? How can this useful in identifying drugs? A spectrophotometry device can emit both UV and infrared light as it measures how a sample either reflects or absorbs. Though ultraviolet spectrophotometry cannot identify a drug‚ infrared spectrophotometry can‚ since the pattern of light is unique to each type of compound. 6.
