SUMMARY The aim is to observe distillation process of ethanol-water solution and to measure the alcohol content after process in this experiment. 500 ml of solution with an alcohol content of 32% (v/v) is used for this experiment. Temperature values are recorded for every 10 ml alcohol obtained in the flask. The process is repeated in our experiment and for the first process‚ the data collection process continues until the distillate reaches to 200 ml. The concentration of alcohol is measured for

Objective 1. To demonstrate the relationship between the pressure and temperature of saturated steam in equilibrium with water. 2. To determine the vapour pressure curve. Introduction Properties of a fluid can change when heat and work are applied to it. There’s an interchange between the fluid and its surroundings when heat and work are applied according to the study of thermodynamics. Substances such as gases and vapors are often referred as P-V-T substances. Theory: An ideal gas

Experiment B10- Photocromism and Piezochromism Reece Harms 4320288 Introduction This experiment investigates an oxidative coupling reaction in an to synthesise triphenylimidazole dimer from 2‚4‚5-triphenyl-1H-imidazole. The resulting compound was investigated for both photochromic and piezochromic properties by way of formation of a stable radical‚ utilizing visual observations and UV-Vis as a means of distinction. Both the oxidative coupling reaction and the dimers interaction with light

DOE - Design of Experiment DOE is an approach used to identify factors/steps that are contributing most to an observed variation in product specifications. The classical DOE focuses on identifying the factors that affect the level of a product/process response‚ examining the response and forming the mathematical prediction model. The modern DOE‚ introduced by Genichi Taguchi in early 1980s‚ applies in both product and process development to identify the factors that affect the variability of the

Is it normally acceptable to experiment on non-human animals to develop products and medicines that benefit human beings? New scientific research has cast grave doubt on the safety testing of hundreds of thousands of consumer products. Everyday products‚ from soft drinks to paints‚ contain numerous synthetic chemicals. Official assurances of the safety of these chemicals are based largely on animal experiments. But recent results from a consortium in America suggested such assurances may be worthless

Purpose: To find the initial velocity of a marble leaving a ramp using time‚ range‚ and background information learned in class. Equipment: The equipment used in this experiment was a toy track and ramp‚ a small marble‚ multiple Physics textbooks‚ meter sticks‚ bright-colored cardstock‚ masking tape‚ sidewalk chalk‚ plastic bag and a cloth. Procedure: Our experimental values include the height that the marble would travel‚ y= 88.1 cm‚ and our ramp angle‚ θ= 44.0°. These independent variables

Brenda Richardson Intro. to Psych. Chapter 6 Part 2 Loftus Experiment Elizabeth Loftus‚ a psychologist and expert on memory‚ has conducted much research on human memories‚ real and imagined‚ and how that may happen. Loftus‚ personally‚ has experienced the misinformation effect and eyewitness memory. Even though there are several experiments outlined‚ I chose the ’Lost in the Mall’ experiment as more fitting to the sex abuse testimony she gave. Participants‚ twenty-four of them‚

The ‘Experiment’ by Dr Haskell portrays the unusual experiment that he conducted to compare his bare body and a Chickadees body in harsh freezing conditions. He decided to investigate it further because there was no logical explanation for a tiny bird to be able to survive in such conditions. He related his astonishment to the Bergmann’s rule‚ which states that larger animals will be found in colder climates and smaller animals will be found in warmer climates. Haskell found that the Chickadees

At first we wanted to figure out if one gender had a better memory than the other‚ but then we also wanted to observe whether or not their memory showed better results when the objects were related to their gender. Therefore‚ the hypothesis we constructed was: If

The wheelchair experiment introduced me to a world that I have never known. I have never been in a wheelchair or been affected by any form of hearing‚ visual‚ or physical disabilities. So‚ this experiment caused me to really think about how the layout of a space‚ weight of doors‚ etc. could affect someone. While using the wheelchair‚ I felt as if I was in the spotlight every time I entered a room or crossed paths with a group of individuals. People would look on as I posed in the wheelchair and give
