insulating materialIntroduction     The experimenter is testing on denim, cotton island of Jersey satisfying, sheepskinfabric, thermal underwear, polyester fabric, and a Ziplock bag with no insulator.From research the experimenter learned that wool is a fine soft wavy hair thatforms individually(prenominal) or part of the protective coat of a sheep. Since ancient measure it washarvested to provide clo amour and is an important part in material mass becauseof its insulation. Woolen fabric is when the woolen system uses short or intricatelong and short fiber where no combing is done. It has a raspy appearance and ismost suitable for blankets, overcoats, and tweeds. Denim which the experimenteris also testing is the material used to make blue jeans and is currently one ofthe worlds most hot fabrics. It is fairly heavy and is made with a bluecotton deflexion and a white cotton filling (Groilers, 1996). The thermal underwearis duofold, with an outside bottom made of 65% cotton, 25% wool, and 10% nylon, andan inner layer made of 100% cotton.     Its the winter again and the weather is becoming colder. individually morningmany people wonder what to wear to stay as warm as possible, but they arentsure which material leave alone forbid them warmest. The experiment was chosen to seewhich clothing insulator retains the most heat. "Insulation is material thatprotects against heat, cold, electricity, or sound." (Science Encyclopedia,1984). In this case the insulation will be protecting against a cold temperature.     The hypothesis is if denim, cotton T-shirt material, wool fabric,polyester fabric, thermal underwear, and a Ziplock bag with out insulatingmaterial are tried to see which one retains the most heat, then wool fabricwill retain the most heat because it holds an important place in todays textiletrade because of its good insulation and the fact that it comes from theprotective coat of sheep who essential to stay warm and use that as their insulator.ProcedureThe first thing the experimenter does is fill the inside of five, gallon-sizeZiplock bags with the insulation material so it is one centimeters dull allaround. Leave the sixth Ziplock bag empty because it will religious service as the controlgroup. Then fasten the insulating materials to the inside of the gallon sizedZiplock bag with adhesive tape.     Next the experimenter boils ten pints of tap water and permit it cool until(using the candy thermometer) the temperature drops to 49 degrees Celsius. Thenimmediately fill each of the six canning jars with equal amounts of the water.Immediately after that drop a unbendable thermometer into each jar, and cap it
