Introduction

Introduction: What my experiment is tying to find out? My Coursework Assignment is to investigate which materials have the properties of an ideal insulator. I have chosen to investigate the effect of insulation on the rate of cooling. The materials I am going to use for the insulation are polystyrene flakes, bubble wrap and cotton wool. The three variables is Insulation because I am investigating the effect of insulation on the rate of cooling. The dependent variable is Temperature because I am investigating the rate of cooling on the effect of insulation. What I know about insulation? I know that heat energy is either transferred or not transferred. There is a difference between internal and external temperatures. The heat energy always flows from warm regions to cold regions. The purpose of insulation is to diminish or prevent this form of heat transfer. All metals are good conductors e.g. iron, brass, aluminum, copper, gold, and silver. ...read more.

periodically and repeat this every minute for 10 minutes for each of my materials. I will implement this data in the form of a table. Here is how my table will be set out : Polystyrene flakes Time Temperature 0 100 1 70 2 65 3 65 4 64 5 64 6 62 7 61 8 60 9 60 10 59 Factors that affect how well an object keeps warm :- Bubble Wrap Time Temperature 0 100 1 60 2 63 3 63 4 65 5 62 6 59 7 59 8 57 9 51 10 49 Cotton Wool Time Temperature 0 100 1 75 2 73 3 72 4 70 5 69 6 68 7 65 8 65 9 63 10 63 How I will make my test fair? ? Thickness ? Colour ? Surface Area ? Volume of water I will keep these factors the same by using the same size and type of boiling tube. ...read more.

Conclusion

? My evidence supports my conclusion. I could have increased the thickness of the material used for insulation and this would give a lower level of heat loss and therefore, the difference between the temperature in the insulated tube and the uncovered tube would be more evident. ? I could repeat my experiment and take an average to increase accuracy. ? Thermometer should not touch the glass; otherwise it is measuring the temperature of the glass, not the water. ? Stirring the water would allow an average temperature to be recorded, not a local temperature. How I can improve my experiment There are numerous amount of ways could I improve my experiment. Firstly I use a digital thermometer because it is more accurate than an ordinary one. The thermometer being digital, records the temperature each second. This gives me a very accurate reading also. I would also repeat the experiment several times to get a broader set of results. And finally I would decrease the time over a time period of 5 minutes so I have a better idea of the rate of cooling.
