# An Experiment to Investigate How Insulation Thickness Effects the Temperature Drop of Water

Extracts from this document...

Introduction

Middle

the sun's rays travel through the vacuum of space to Earth through Wave motion. This experiment was conducted with a black can, presuming the can is painted black inside means that it absorbed the warmth of the water through radiation waves into the walls. If black was the colour inside the can it quickened the process of heat loss whereas if the can had been sliver inside it would reflect the radiation waves back to the water prolonging the heat contained. If you were to continue the investigation would the patterns continue? If I was to continue with the investigation I think judging from the graph the patterns will continue to a point until it levels off. Past a certain amount of layers there will be no decrease in the temperature drop as the water will reach the point were an extra layer makes no difference. This is because the water will have reached the maximum point were the average temperature drop will not change as the can not retain any more heat than it was already.. EVALUATION How good is the experiment? The experiment shows an approximately clear rate on how insulation effects the temperature drop on water. The experiment was done more than once on each layer to provide a more accurate average and precautions such as measuring the thickness of the bubble wrap so it would always be the same size tried to ensure that the experiment was fair. ...read more.

Conclusion

I think the results have allowed me to make a firm conclusion because they have produced the patterns I expected. They may be slightly inaccurate here and there but these inaccuracies do not effect the experiment to the extent all the results are abnormal. If you were to repeat this experiment what would you change and why? As an improvement to my experiment I could have used a clamp, boss and stand to place the thermometer accurately especially when there isn't a lid to support it to stop any inaccuracies caused by this. Perhaps it would also be a good idea if the bubble wrap were made marginally thicker before it was wrapped around the can as when it is compressed it will become smaller and go to the correct size. I also think a note of the room temperature should be made just to be aware of an outside factor that may effect the results. How could you extend this investigation? I could change the material of the can to see if it affects the rate of which heat is transferred and I could also change the insulation properties by using cling fling or cotton wool to see what difference they make to the temperature loss. You could keep adding layers to see the point were it makes no difference. In addition, you could investigate the experiment without the plastic lid to see the difference the loss of heat through convection currents throughout the experiment changes the results. . ...read more.

This would have made the results more accurate. This is because the beaker of water would have lost heat prior to starting the experiment. From this trial run I have learnt to be more accurate with the timings between readings. Hopefully, this will make my results more valid and accurate in the main experiment.
