Abstract The experiment conducted was to analyse the work of a heat exchanger‚ by studying the effects of heat transfer from a hot stream and a cold stream in the heat exchanger. In the experiment we were introduced to the shell and tube heat exchanger and were told of all its parts and how to use them. The experiment started by evaluating what the heat transfer rate for a hot stream and a cold stream was within the heat exchanger. Using this information the experiment went on to analyse the heat

next. The climate of England is variable and changes from day to day‚ and it is hard to forecast the weather. The climate in England is entitled temperate maritime. This means that winters can be milder than 0 degree Celsius and summers are usually not much warmer than 32 degree Celsius (Barrow‚ 2012). There are four seasons in England - summer‚ autumn‚ winter and spring. Therefore‚ people who live in England should have clothes for weather that can change frequently. On the other hand‚ Thailand

how to build an incubator. The microbes in this experiment have different temperature requirements: one type is best grown at room temperature while the other requires a temperature similar to that of our physical body (between 35 and 37 degrees Celsius). The second step is to select the appropriate medium for the specified microbe. In this experiment we will use a liquid broth medium for both cultures. The first is MRS culture medium‚ which contains polysorbate‚ acetate‚ magnesium and manganese

Temperature is a measure of the average kinetic energy of the particles in a sample of matter. The greater the avg. kinetic energy of the particles in a sample of matter‚ the higher the temperature of that matter. Some temperature scales are Fahrenheit‚ Celsius and Kelvin. Thermal energy is the measure of the total kinetic energy in a sample. And Temperature is a measure of the average kinetic energy. Ex: Which container (the bath tub or the coffee cup) have a temperature that is higher than the other

In this lab‚ the class tested the effect of temperature on the rate of fermentation in yeast by measuring the height of CO2 produced in a graduated cylinder at varying degrees Celsius. Yeast can perform cellular respiration and fermentation‚ the first needing oxygen (aerobic) and the second not (anaerobic). Cellular respiration is the normal way human bodies’ make energy‚ but when lacking oxygen‚ cells undergo fermentation‚ which creates less energy than respiration‚ CO2‚ and lactic acid (though

organic layer that would be used for simple distillation. The distillation apparatus separated the dichloromethane from the methyl benzoate by difference in temperature. The Methyl Benzoate could only be achieved when the temperature climbed to 198-199 Celsius. The product will be obtained if the steps are taken very carefully and accurately. Reagents: 3.72 ml (4.9 g‚ .041 mol) of Benzoic Acid 12.5ml (9.89g‚ .309 mol) of Methanol 1.5 ml of Sulfuric Acid 1.5ml (1.63g‚ .012 mol) of Methyl Benzoate
