Introduction

G.C.S.E science coursework Coursework: Insulator Aim: My aim is to find out which is the most effective insulating material out of a range of different materials. Introduction The choice of an insulation material is usually made depending on the application. Polyethylene and polystyrene are usually used in high-frequency applications. Insulators must also be selected according to the maximum temperature they will encounter. I.E. Teflon is used in the high-temperature range of 175� to 230� C. Other materials may need to be used in awkward mechanical or chemical conditions. Nylon has an excellent abrasion resistance, also neoprene, silicone rubber, epoxy polyesters, and polyurethane's usually provide protection against chemicals and moisture. Thermal insulating materials are used to reduce the flow of heat between hot and cold regions. The sheathing often placed around steam and hot-water pipes, for instance, reduces heat loss to the surroundings, and insulation placed in the walls of a refrigerator reduces heat flow into the unit and permits it to stay cold. Thermal insulation may have to for fill one or more of three functions: 1. To reduce thermal conduction in the material, in which heat is transferred by electrons. 2. To reduce thermal convection currents, which can be set up in air- or liquid-filled spaces 3. To reduce radiation heats transfer, where thermal energy is transported by electro-magnetic waves. ...read more.

I will initially record my results in a table that can record , which material has what temperature after how many minutes. I will carry out two sets of experiments inside my investigation, so recording two sets of results so that I will be able to compare, contrast and work out the averages. Having two sets of results will help me to make sure that I have not obtained any 'freak' results. For the first and the second sets of results I will construct: a bar chart with the line of frequency, a pie chart, a table and line graph that will tell the observer the averages from the two sets of results. I will repeat the experiment once, making it that I would have performed the experiment twice. Apparatus 3 larger sized tins - (if there is a choice) 3 three different materials - to use as insulation materials some cardboard - to construct a lid 3 elastic bands - to hold the cardboard lid on to the tin a roll celetape - to fasten the insulating materials on to the tins. 3 measuring cylinder - to measure the amount of boiled water going into the tins. ( I will choose to put 200 ml in to the tins Kettle and water - I will (obviously) ...read more.

Conclusion

but I could have made my results more accurate if I had fine-tuned my experiment. If I were to repeat this investigation these are the changes that I would make to my experiment: 1) All of the tins would have had a top and a bottom made of the particular material. 2) I would have ran the experiment on to a 30-minute temperature check. 3) I would carry out at least one set of tests that were set in the dark to avoid any interference from the heat loss method of radiation. 4) Wrap the material twice around the tins. 5) Add more or less boiled water. 6) Try and speed up the process of getting the boiling/boiled water from the kettle to the tins. 7) Repeat the experiment for years and years so then I could 1 improve the experiment and 2 get more accurate results, really a group of people would have to keep the experiment going on for ever to know the true outcome, nobody knows what it would be. 8) (realistically) Repeat the experiment more then 5 times for each variable to get a more accurate answer. 9) Change the material of the tins. 10) Use many different materials. To find out more and to get a far more accurate answer for finding a good, or the best insulator from everyday materials I would change as many variables as possible. But to improve my investigation the issue that would need addressing would be to improve my accuracy. ...read more.

    The thickness and density of the material will also have a significant impact on the materials efficiency. Air is a very poor conductor, so materials with lots of large air pockets will be good insulators i.e. the bubble wrap. For the material to have lots of air pockets it has to be less dense and quite thick.
