For our project, we have chosen water and its cooling effects 'To Keep The Can Drinks Cold'.
Question: How will the water/different types of water cool the can drinks?
- Well, during our research, we found out that if a hot object is immersed in cooler water, heat will transfer through conduction and convection. The process removes heat energy from the object and cools the object. So we figured that if we place the cold can drinks in the cold water/s, it will be remain cooled.
We also figured maybe if we had used different types of drinks - mineral water, orange juice, soda(randomly choosen); it would maybe keep the can drink cool at a longer or shorter period.

Thanks for your clarifications. While the first quote about water being able to cool a hot object, the mechanism of this may not work with cold objects - you will need to read up on what makes a cold object warm when left at room temperature. As for trying out the effect of juice, etc, are you thinking about soaking the canned drink in the juice? If so, why are you trying out the effect of different liquids? Your research does not seem to provide any info on this. In other words, the aim of your experiment does notmseem to make any sense. It's like trying to investigate which color wrapper makes the same sweet taste better (of course, it does not make any difference).
