  • Five Values For Temperature And Pressure
    1,221 words
    Aim: To find out the effect of temperature on the pressure of air. Apparatus: 400 ml beaker Bunsen burner Data Logger Pressure sensor Temperature probe Round bottom flask Connecting leads Tripod Gauze Plastic tubing Clamp stand Heatproof mat Water Diagram: Method: 1. Set up the apparatus as shown in the diagram. 1. Next, take the readings of the pressure and temperature at intervals of 5 C, ending the experiment at 90 C. 3. Repeat the experiment three times for a good average. 4. Record all resu...
  • Ideal Gas At Standard Temperature And Pressure
    2,690 words
    Chemistry Independent Study: Gas Laws Gas Laws Since the days of Aristotle, all substances have been classified into one of three physical states. A substance having a fixed volume and shape is a solid. A substance, which has a fixed volume but not a fixed shape, is a liquid; liquids assume the shape of their container but do not necessarily fill it. A substance having neither a fixed shape nor a fixed volume is a gas; gases assume both the shape and the volume of their container. The structures...
  • Boiling Point
    586 words
    Fractional Distillation of Crude Oil BOILING POINTS AND STRUCTURES OF HYDROCARBONS The boiling points of organic compounds can give important clues to other physical properties. A liquid boils when its vapor pressure is equal to the atmospheric pressure. Vapor pressure is determined by the kinetic energy of molecules. Kinetic energy is related to temperature and the mass and velocity of the molecules. When the temperature reaches the boiling point, the average kinetic energy of the liquid partic...
  • Temperature Pressure Relationship In Hydrogen
    1,360 words
    Hydrogen: the most abundant element in the universe. Normally it has been considered to remain anon-metal at any range of temperatures and pressures. That is, until now. Recently this year, hydrogen was changed into a metallic substance, which could conduct electricity. An experiment conducted by William J. Nellis et al. at the Lawrence Livermore National Laboratory accomplished this feat. Hydrogen was converted from a non-metallic liquid, into a liquid metal. The likelihood that the most abunda...
  • Complete M Jannaschii Genome
    614 words
    ts, and biochemical pathways. In comparing the organism 60% of M. jannaschii's coding regions did not correlate with the known sequence database. 40% of the coding regions match the sequences of bacteria and eukaryotes. Those sequences that are similar to bacteria are genes related to energy production, cell division, and metabolism, whereas the transcription, translation, and replication gene sequences seem to be more similar to eukaryotes. EM / Methanococcus jannaschii / EM consists of three p...
  • Force Of Attraction Between Gas Particles
    1,777 words
    Chapter 13- States of Matter Gases Kinetic Molecular Theory. Model to describe properties of gases. Kinetic = move. Theory describes behavior in terms of particles in motion. Model makes assumptions about size, motion, and energy of gas particles Particle size. Gases consist of small particles that are separated from one another by empty space. Because gas particles are far apart, there are no significant attractive or repulsive forces among them Particle Motion. Gas particles are in constant ra...
  • Boiling Point For Cyclohexane The Distillate
    654 words
    INTRODUCTION: Simple distillation is a process to purify volatile compounds or compounds with different boiling points. It is a simple process that takes a mixture of compounds and applies heat. The substance with the lowest boiling point, (usually the most volatile), will boil and vaporize first. Using a distillation apparatus consisting of a flask, glass tubes, thermometer, condensing tube and distillate container, the first gaseous vapor that rises can be condensed back into liquid. This liqu...
