Osmosis Experiment Subject: Professor Egg-avier Duration: 3 weeks (Oct 2nd – Oct 16th) Week 1 On October 2nd my group was giving a raw egg (weighing 58.8 grams) and placed it into a clear mason jar with 200mL of vinegar. The ph levels of our vinegar equaled a 2 which tells us that vinegar is a fairly acidic liquid. Once submerged in the vinegar‚ little bubbles began to appear around the egg’s shell. We believed this to be carbon dioxide escaping from the shell. We left our egg to sit in the

"MEASUREMENT" is the determination of the size or magnitude of something "Or" The comparison of unknown quantity with some standard quantity of the same rates is known as measurement. Due to this fact we have standards of measurement. Since the precision of all measuring

Sedentary Population’ is essentially an infrared dry sauna‚ the heaters produce infrared rays that superficially heat skin and other exposed surfaces but not the air.[7]‚ which is absorbed by the surface of the skin.[1] A study of patients with rheumatoid arthritis and ankylosing spondylitis showed a reduction in pain‚ stiffness and fatigue during infrared sauna therapy. [2] According to some users and scientific studies‚[3] regular usage of the IR Sauna can assist in alleviating pain. The heating of the

UV4297 March 24‚ 2010 THE ABERDEEN EXPERIMENT The phone rang yet again‚ but Sarah Mann‚ general manager of the BAE Systems plant in Aberdeen‚ South Dakota‚ was ready. Experience told her what the question would be: Had the “Aberdeen experiment‚” begun by Bob Lancaster when the plant was built‚ undergone any changes over the past quarter century? From the beginning‚ Lancaster’s design and management of the plant‚ which produced missile launch canisters for the U.S. Navy‚ were unusual—and successful

Calorimetry Experiment Purpose: The objective of this lab is to determine the enthalpy change for NaOH(aq) + HCl(aq) NaCl (aq) + H2O(l) Procedure: Before measuring the enthalpy of acid base neutralization‚ my partner Brian and I determined a calorimeter constant‚ using a homemade polystyrene calorimeter. With the following formula and data: qhot= cm (Tf-Ti) qcold=cm(Tf-Ti) SYSTEM DATA SURROUNDINGS DATA Water cold Mass: 50mL Water hot Mass: 50mL C=4.18 C=4.18 Ti=20 C Ti=31

Introduction The objective of this experiment is to combine Magnesium (Mg) with hydrochloric acid (HCl) to determine the molar volume of hydrogen gas (H2) (converted to the molar volume at STP) and then‚ to compare obtained results with the molar volume of an ideal gas. To determine the measured molar volume of hydrogen gas‚ we are going to use this equation: The molar volume of the ideal gas will be determined by the equation ‚ where T = 237 K‚ P = 101.3 kPa. The hydrogen gas will be collected

The Sensorial Area “There is nothing in the intellect which is not first in the senses.” Aristotle We as human beings have been endowed with the unique gift of intellect. We are considered the top of the creation because of this intellectual ability to reason. Each human is born with the potential to have and use the intellect‚ however‚ intellectual maturity‚ like physical maturity grows as a result of good nutrition and plenty of exercise. The senses are the food of the intellect. The concrete

The Twin Experiments was conducted by Josef Mengele‚ during World War 2 in Auschwitz. Dr. Mengle was a medical researcher who was fascinated with twins in specific. From the three thousand children that would be pulled from the masses of people upon arriving only about 200 survived. Age didn’t matter‚ yet most were children‚ and if they were really young their mother would be allowed to stay with them. The twins recieved "special" treatmeant as they were allowed to keep their hair and clothes. A
