Find out if the volume of water would effect the rate of cooling within a polystyrene beaker

Extracts from this document...

Introduction

Purpose of Investigation The purpose of this investigation was to find out if the volume of water would effect the rate of cooling within a polystyrene beaker and also if the use of a lid would effect it further. Presumed Method I firstly predicted that the beaker containing lesser volume would remain the hotter throughout the experiment, I also assumed that the use of lids would make the water remain hotter for the duration of time.The scientific knowledge that I based this on was that of insulators and conductors, I thought that using the lids would contain the heat causing it to remain hotter for longer. ...read more.

Middle

Method Firstly I collected the apparatus that I was going to use: Two polystyrene beakers Two lids Two thermometers Measuring Jug Stop watch 900ml of hot water After I measured 300ml of hot water and poured it in to one beaker, then, measured 150ml of hot water and poured that into the other beaker. After placing in each beaker a thermometer I then proceeded to write down the temperature of each beaker every 2 minutes with the use of the stop watch. After 30 minutes of recording temperatures, I then proceeded to the second experiment, where I measured the same amounts of hot water ...read more.

Conclusion

Conclusion When the volume of water was more the water stayed hotter for longer and when it had a lid it stayed hot even longer this proves that polystyrene is an insulator for also the outside of the beaker was not hot to touch even when the water was at boiling point. This gives us reason to why McDonalds uses this material for their hot drinks beakers as they to not conduct heat they insulate it. ?? ?? ?? ?? To determine whether volume and the use of lids effect the result using polystyrene beakers. ...read more.

    and surroundings. This law also describes that the rate of heat transfer from a solid surface into a fluid medium. The relationship for the energy flow rate due to convective heat transfer at the interface between a solid object and a fluid environment is referred to as Newton's Law of Cooling.

    As the warmer water particles begin to rise, the cooler water particles at the top of the beaker will sink to the bottom, as they are less dense. Once at the bottom of the beaker they will start to get warmer and become less dense.

    My results tell me that the water evaporates slowly until the biggest energy molecule leaves. It continues to decrease in temperature at the end of the experiment then the graph begins to show a certain pattern. The pattern is a smooth curve and most plots do not follow the pattern.

    So, therefore the fewer numbers of layers I use the quicker the rate of cooling. This is what I think will happen. Because I am using 'bubble-wrap' as my insulator the 'bubbles' in the material have trapped air in them.

  2. Why Insulate Houses?

    We decided to do this as; water has a high specific heat capacity that would be easier to monitor than something with a lower SHC! It would be necessary to have a preliminary test to see how long the water would take to cool etc.
