Find out what insulator is the best from cotton wool, bubble wrap and plastic foam.

Extracts from this document...


Aim: We are trying to find out what insulator is the best from cotton wool, bubble wrap and plastic foam. Plan: The factor I will be changing is the type of insulator. The factor I will be recording is the temperature of the water in degrees for a total of six minutes. To record the temperature I will use a thermometer. The factors I will keep the same so it is a fair test are: Starting temperature of the boiling water Same amount / volume of water Measuring the temperature at the same interval Covering the same amount of surface area, length and width for each insulator. I intend to wrap three testubes with the chosen insulators, but leave the last one plain for control. Cotton wool Bubble wrapping Plastic foam I have also chosen to do a control experiment without insulation to see if there is a great difference in the heat loss if the container has insulation. I will then boil some water and when it is boiled I will carefully pour it into a measuring cylinder up the chosen volume (20cm�). I will pour it into the containers and allow it to cool to the chosen starting temperature. Once it reaches the chosen starting temperature then I will start the stop clock and record the temperature at chosen intervals. I will repeat this procedure for the next two containers. I will then repeat the whole experiment one more time to be sure that my results that I will obtain are reliable and reproducible. ...read more.


There is nothing to transfer the energy from the sun to the earth. The sun's rays travel in straight lines called heat rays. When it moves like that, it is called radiation. When the sunlight hits the earth, its radiation is absorbed or reflected. Darker surfaces absorb more of the radiation and lighter surfaces reflect the radiation. So, if you wear light or white clothes outside during the summer, you would be cooler. The below diagram relates to my prediction because I am not investigating colour or day or night. I think that cotton wool would be the best insulator because cotton wool has little pockets, which can trap air into the pockets and air, wouldn't be released because air is a very good insulator. The next insulator I think is going to be the best is bubble wrap. I think this is going to be the next best because it has little bubbles, which can trap air, so no conduction radiation or convection can take place. So therefore, no air can be released. The next insulator is plastic foam. I think that this is a good insulator because it has many pores that can trap air. In addition, air is a very good insulator. Therefore, no conduction convection or radiation can take place. Conduction of heat is the process where vibrating particles pass on their extra vibration energy to neighbouring particles like shown below: Safety Safety measures are needed because I am dealing with hot water, which can injure. ...read more.


Evaluation: My method was not 100% a fair test as you can see from my graph. Some of the reasons why there might be errors are: The water might not have been measured properly because numbers might have been rubbed off from the measuring cylinder The timing might have been wrong The insulation might not have been wrapped properly The water might have lost heat before starting the experiment Same testube might have been used for the experiment The same surface are might not have been covered The equipment and procedures that could have been used to get accurate results are: Digital thermometers Digital clocks The results were good to support my conclusion. Even though there were some errors. Some of the reasons why there might be errors are: The water might have lost heat will we were waiting to reach the temperature wanted The timing might have been wrong Different surface area might have been covered If I was to do this experiment again I would: Make sure the same surface area was covered The same thickness of each insulator If I were to do the experiment I would use different factors some of the different factors are: Material - foil, paper, plain copper Colours - black, white and other colours.
