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. I thought that what I would need was the two polystyrene beakers, two thermometers, a stop watch and approximately 900ml of water. The way I assumed I would go about conducting the experiment was to fill each beaker with the appropriate volume of water and use the thermometers to measure the heat decrease every 2 minutes.
