Objective:
Observing the reaction of dissolving tablets in different temperatures of water.
Data:
The cold water was 20℃, and the hot water was 60℃. It took exactly 2 minutes and 4 seconds for the tablet to dissolve in the cold water. It took 20 seconds for the tablet to dissolve in the hot water. These results explain that the higher the temperature the faster the reaction will occur.
Analysis:
Water molecules move faster in hot water than in cold. The reason why the tablet dissolved faster in hot water is because of the increased molecular motion. The added energy caused the water molecules to move faster. Because these molecules move quicker at higher temperature, they collide more. Since they collide with each other more, the reaction
