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.

    Water was boiled and put in to the two beakers, and stopwatch started. 5. Results were taken every 1-minute, for a total of 30 minutes. My results are as follows: Time Temperature of Temperature of (Minutes) Bubble wrap (degrees)

  2. Factors Affecting Cooling

    This was because the biggest beaker had the most surface area touching the water. Therefore more water molecules could collide and touch the beaker. If molecules lost heat through convection and radiation through the glass then the more molecules touching the glass, the more radiation.

  1. In this investigation I will investigate heat loss and heat transfer in different materials ...

    I stated in my prediction that from my own knowledge that any material, which is black, will be a poor insulator as it transfers heat away rather than keep it in.

  2. I am going to investigate the rate of cooling in heated water. In my ...

    because having lost the molecule with the biggest energy the average kinetic of the liquid molecules is now lower than before and temperature depends on the average kinetic energy therefore the temperature is lower. Evaluation. My procedure was very good and everything went to as according to plan because I did 2 trial runs to make my procedure was correct.

  1. Why Insulate Houses?

    We will wrap cotton wool or another fabric around the beaker in certain places reflecting areas insulated in the home. From this we can plot a cooling curve. In theory the most efficient insulator will have the shallowest cooling curve.

  2. To find out which type of insulating is the most efficient at keeping in ...

    It is the emission of heat waves. Heat- Form of energy possessed by a substance by virtue of the vibrating movement (kinetic energy) of its molecules or atoms. Heat energy is transferred by conduction, convection and radiation. It always flows from a region of higher temperature (heat intensity)

  1. To investigate the effect of insulators on the rate of cooling.

    So that you can`` - And note down the temperature every 1 minutes. Until 10minutes. In this experiment I will be measuring the temperature drop every one minute. I will do this by having a stop-clock to measure the temperature at exactly two minutes each time.
