Moving Molecules!
By Jasmine Turner
Introduction I am going to be using a uncomplicated experiment to see if hot water molecules really do move more rapidly than cold water molecules. The reason for conducting this is experiment is the uncertainty of whether hot water molecules, (being able to go at a faster rate) would spread easily enough to beat cold water molecules. To perform this experiment hot water and cold water will be placed in separate glasses with food dye to see which type of molecules spreads the dye around first.
Hypothesis: The main point of this experiment is to discover if hot water molecules move faster than cold water molecules. I believe that the hot water molecules will progress quicker than the cold water molecules because heat will extend the molecules around the glass to dissolve them.

Conclusion In conclusion my hypothesis was precise and hot water molecules do move more rapidly than cold water molecules due to the difference in speed. Upon placing the food dye in the glasses I considered that cold water molecules would be quicker because they looked like they were spreading without difficulty while the hot water molecules seemed to resist. As the experiment was taking place the cold water molecules became unhurried and the hot molecules stayed unchanged in speed, letting them spread first.
