Melting point 1. What two effects do impurities have on the melting point of an organic compound? Soluble impurities affect the melting point of a solid in the following manner. a. The presence of an impurity in the molten compound reduces its vapor pressure thus lowering the melting point of the compound. b. Broaden the melting point range. 2. For what tow purpose are melting points routinely used a. To determine the identity of an organic solid. b. To determine the purity of an organic solid

Gas Pressure and Volume Relationships Exp. E-1A A. Obtain a pressure-measuring device as indicated by your lab instructor. Obtain a 60 mL syringe‚ fill it with air‚ and connect the syringe to the gas-measuring device as indicated in the figure. Test your apparatus for gas leaks. If you can’t eliminate all leaks‚ see your lab instructor. B. If necessary‚ calibrate your gas-measuring device as indicated by your lab instructor. Fill your syringe to the largest volume mark on the syringe and reconnect

Society’s Pressures It was a frigid morning in the arctic circle‚ as was every day. Noelle had just awoke from her slumber‚ careful to not disturb her husband‚ Dan. Noelle had slept poorly the night before‚ deep bags located under her eyes showed that. She was worried‚ for the holiday season was fastly approaching and Noelle had nothing‚ but herself to offer her husband. Well she also had two little lanternfish tucked away. Though the fish would look hysterical on the prized china Dan uses every

CALIBRATION OF TEMPERATURE AND PRESSURE SENSORS Mechanical Engineering Department Loyola Marymount University Los Angeles‚ California ABSTRACT In this laboratory experiment‚ an Omega Model PX- 236-060GV piezoresistive pressure transducer was calibrated‚ by using an AMTEK model deadweight pressure tester. For the temperature calibration an Jofra Model C-140 temperature calibrator was used. The experiment began by setting up the Jofra Model C-140 temperature calibrator‚ and taking data from

women recorded their heart rate and blood pressure under different conditions. In Figure 1‚ the blood pressure data of an individual female in very good condition is shown under the effect of posture. Figure 2 shows the blood pressure data of the same well-trained female under the effect of exercise. The individual data in both figures 1 and 2 fell outside the standard error of the mean for the class. Figure 3 shows the class data (N=335±3) for blood pressure under the condition of exercise.
