Keysville‚ VA. Contact: huntertuck1212@gmail.com Abstract This particular study demonstrated the overall effects of super cooling different types of aqueous solutions. In similar studies conducted upon super cooling water‚ researchers have only used distilled water in their experiments. In this study‚ however‚ rain‚ tap‚ and purified bottled water were used. The researcher’s prediction was that if energy was introduced to each of the super cooled aqueous solutions‚ then nucleation would occur similarly

Heat resistance of endospores of Bacillus pumilus Abstract Spore suspension of Bacillus pumilus was inoculated into universal bottles containing sterile distilled water in water baths at temperatures of 85°C‚ 90°C and 95°C. At specific time intervals‚ a sample was removed and spread on nutrient agar plates. The number of colonies formed was used to determine the D-value and z-value. The D-value for 85°C is 64.1 minutes‚ 25.7 minutes for 90°C and 8.2 minutes for 95°C while the z-value is 11

chemical compound that changes color and structure when exposed to certain conditions and is therefore useful for chemical tests. The purpose of using distilled water as one of the substances in the test is that it’s the control; it should never be positive since it has no organic compounds. The control group in part c is the 5 Ml of distilled water. The purpose of washing the test tubes thoroughly is so you don’t mix substances‚ which can cause your results to be inaccurate. Hypotheses:

Step #3: Determine the percent error. 3.0 X 10-4 – 1.92 X 10-4 X 100 = 36% 3.0 X 10-4 Step #4: Determine if batch 021015 meets legal requirements Is it in the range of 2.85x10-4 and 3.15x10-4?? Exercise #2 Step #1: Fill a 100ml beaker with distilled water and add 20 drops of blue dye #1 and stir. Add more drops of blue dye to solution if it is not darker than your commercial dye. (I added an extra 20 to make mine darker) This gave me a concentration of 5.2x10-4. Record concentration Step #2:Place
