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

The article begins by explaining a basic plot of a sci-fi movie in which the main character has had his memories altered by scientists using electrode caps. The article then goes into detail about how a new set of experiments‚ led by MIT neuroscientists

Water Pollution Water – The Elixir of Life Can you imagine life without water? Take a minute and think about it. We need water for all our daily essential activities – drinking‚ bathing‚ cleaning… In fact‚ every living thing on this planet needs water Water pollution And what do we do with this vital resource? We take its all important ability – we all know that water can dissolve many of the thing that we dump in it – to make it a giant rubbish bin. In fact‚ we even throw things

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

preparing some potatoes for cooking. He put some water in a pot and added some salt. He cut up the potatoes and put them in the salt solution. Then the telephone rang and he spent 30 minutes talking to George. When he returned to put the potatoes on the stove they were flaccid (soft). Explain what happened to the potatoes. The concentration of free-moving water molecules is higher in potato cells‚ the cytoplasm of the cell is hypertonic. The water molecule will flow from higher concentration to lower

Introduction In this investigation‚ me and my partners performed an experiment to find the different energy contents in food and different amounts of energy released when consumed. Throughout this experiment our procedure was to take different food samples and use a device known as a calorimeter made from a can of aluminum‚ one large paper clips and a string of copper wire to measure the amount of thermal energy released during a reaction. By measuring the temperature difference before and after

It talks about sensory adaptation and how adaptation is evident in each of the experimental results. It also provides a comprehensive description of the sensory systems in the experiments that I performed. Before starting the four experiments‚ I had to remember that I had to keep in mind that there are five
