# What Factors Affect The Cooling Of A Liquid

Extracts from this document...

Introduction

GCSE Coursework Investigation: What Factors Affect The Cooling Of A Liquid PLAN Variables * Amount of liquid * Temperature of surroundings * Shape of container * Material of container * Colour of container * Size of container * Surface area of container * Temperature of liquid to start * Type of liquid * Density of liquid * Surface area : Volume of liquid * Surface container is on * Thickness of container * Lid or not * Insulation * Time These are the variables that I could choose to focus on. I have chosen to focus and adapt on the idea of insulation. Prediction I predict that the more insulation (layers) there is, the smaller the reduction in heat. I think this because when the outside air tries to touch the container to cool it, it will be stopped by the insulation, so it will take longer to cool. Also, when heat tries to escape from the container, it will go into the first layer of insulation, which will then absorb the heat. It would then still keep the container warm, not letting as much heat out as fast. I also predict that if I have a lid it will take even longer to cool, because, as you can see in the picture below, evaporation will also take place. ...read more.

So I will, once the kettle has been boiled, wait for five seconds and then pour directly into the glass beaker. * Insulation- the type of insulation I am going to be using will have to be the same. Therefore, before my experiment I will cover the glass beaker with 5 layers of insulation, and take one off at a time. * Thermometer and Data logger- I will put both the thermometer and data logger in the glass beaker at the same time to make sure that there is no difference between the temperature of the water. * Taking the insulation off- I will have to make sure that when I have finished 5 layers and I take one layer off, I don't accidentally take two or three off. Also once I have taken a layer off, I will run cold water from a tap on it for 1 minute, this is to ensure that the remaining heat in the glass will not heat up the water when I put it back in. Range The range I am using is from 1 layer of insulation to 5 layers of insulation. I think that this will give me conclusive results. ...read more.

Conclusion

* Boil the kettle away from the experiment. * Put a layer of insulation under the lid and swap it after each experiment to prevent the lid from getting wet. * * I could have made my experiment better and more conclusive if I had had a larger range, maybe go up to 10 layers; because some of my results seemed to make sense but there were some that didn't fit the pattern. If I had had a larger range I would have been able to get more evidence that would enable me to support my conclusion. Also if I had had time I would have re-done some more results as I have quite a few odd results and then I could have compare these to my results to see which ones were accurate and which ones weren't. The odd results I got were probably due to the errors I made and bad accuracy. Conclusion The pattern was that the more insulation layers the smaller the heat reduction. This is what I put I put in my prediction. Although this didn't happen in all of my results it happened in some. Mrs Ford- GCSE Coursework Laura Macleod- 10PT - 10SC1 - 1 - ...read more.

Air offers about 15,000 times as much resistance to heat flow as a good thermal conductor such as silver does, and about 30 times as much as glass. Typical insulating materials, therefore, are usually made of non-metallic materials and are filled with small air pockets.

convection current; warmer, less dense particles rise, then cool and fall back down again where they become warmer etc. The fact that there will be a convection current means that heat will be spread around the cup.
