Introduction

Aim : To investigate how changing the volume of water in a container affects its rate of its heat loss. The variable of this investigation is the volume of water which is put in the container. What I already know: I already know that the larger the volume of water there is the less heat loss occurs. I can tell this from my previous pilot experiment where I investigated, if the volume of water in a beaker affects its rate of cooling. In this experiment my conclusion was the beaker with the larger volume has no more heat energy to give out compared to the beaker with the smaller volume. Prediction: I predict that the increase of water volume in the beaker will affect the rate of heat loss; this is because of my results of the pilot experiment which gave me an understanding of the variable in my Investigation. ...read more.

Middle

Take a reading from the thermometer every 30seconds, remembering to record results in a table. * Repeat this until all volumes of H2O has been investigated, but still using the same beaker for the next amount of water so it will be a fair test. * A few pointers of fair testing: 1. Remember to make sure that the thermometer is upright so you can take an accurate reading. 2. Make sure the Bulb of the thermometer is covered in the boiling water. 3. Make sure when investigating a different volume of water you get the thermometer back to the same starting temperatures as the previous volumes. * This is How I will display and record my results: Time Temperature 0 73 30 68 Analysis Trends and patterns: The 100ml line, the 150ml line and the 200ml line have approximately 4 degrees difference from 240seconds into the experiment .This is because convection is happening relatively at the same time for each one. ...read more.

Conclusion

Another way to say the same thing is that the rate of heat transfer through a substance is proportional to the difference in temperature across the substance. They are not odd results they do fit in with the pattern this is shown on my graph. I could improve my plan by maybe having two or three variables these would make my investigation more detailed and perciffic.I could check this trend/patern by making another graph with just a single line of a water volume to show at which point does convection start to fade at. The next experiment I could do to proive my varaible would be if I did the same experiment but actully covered the top of the beaker to prevent evapouration, to see which volume took the longest to cool down. ...read more.

    successful collisions ids greater, resulting in a larger increase in the rate of photosynthesis between higher temperatures like 15 oC and 25 oC and an even higher increase between 25 oC and 35 oC.

    These factors will help to reduce heat loss. If a lid is used: If a lid is used then it will obtain more heat as it will not be able to escape the container. The heat will rise in a gas form then it will condense on the colder surface of the lid.
