The rate of Cooling of water with different Insulating materials

Extracts from this document...

Introduction

The rate of Cooling of water with different Insulating materials Aim I Aim to find out which is the best insulator out of several different Materials. I also would like to find out if Common Insulation methods are effective in preventing heat loss. Insulation There are many different kind of insulation. I'm using a method called thermal insulation where I use materials to stop the loss of the heat by radiation. Air is one of the best insulators so materials with more trapped air in should prove to be the most useful. I will try and prove this fact. Plan I'm going to put boiling water into 5 beakers wrapped with different Insulating materials. I will record the temperature every 3 minutes for duration of 24 minute. After that I analyse the data and come to a conclusion. Diagram 5 Beakers wrapped with different insulators. and a Kettle to pure the water and 5 thermometers to record temperature Equipment 5 Beakers Aluminium foil Bubble wraps Synthetic fur 5 thermometers Black felt 5 rubber bands 5 cardboard lids Kettle Safety I will be careful when handling the hot water and use proper pouring equipment. ...read more.

In both the first and Second set of results this turned out to be true. Patterns The main pattern is that most of the temperatures dropped by 1-3 degrees each time. Problems I sometimes had trouble keeping the lids the on beakers. I also put the wrong amount of water in one of the beakers the first time I did the experiment. Also one thermometer broke and I had to use 1 between 2 beakers. Accuracy The first sets of results were accurate apart from the just glass beaker, which had the wrong amount of water in it. I some results may be odd because of the difficulty keeping the lids on. ...read more.

Conclusion

I would have like to have used foam in this experiment to see what kind of insulating effects it has. I would also have like to try combining different materials to see what kind of a different that would have made. But the general experiment went well and I am happy with the results and my findings. Maybe if I had kept the experiment going for longer there may have been considerable differences in my results. I'm a little bit unsure about the Results for the bubble wrap. I really expected that to insulate better than it did. The problem keeping the lid on may have affected it. That is something I should think about when repeating this experiment in the future. Another thing that I think about is what if all the starting temperatures where the same. I'm sure it would not have made that big a difference, but you can never be sure. I may have missed a peak drop or the temperature may have dropped faster at higher points. These are toher things for me to think about. Overall I'm happy with the results and I would call the experiment a success. But there is room for improvement. ...read more.

    Investigating the rate of cooling water in a beaker.

    The reason why my results quiet clearly the effect of insulation on the rate of cooling water is because there was hardly any other way by which heat could be lost other than evaporation. However evaporation was not possible since a card that was placed on top of both beakers was preventing it.

    The evidence obtained was just as expected it agreed with the pattern of relationship. The accuracy of the results is very good. I did find some anomalous results on my experiment and found out it caused by the convection current occurring.

  2. Factors Affecting Cooling

    If that air is cold then the heat will radiate from the glass at a quicker rate as there is a bigger gap between the temperature of the air and the temperature of the glass. If that air was warm then the heat will radiate slower as there is a
