My hypothesis was the the warmer the temperature, more of the chemical reaction will take place because there will be more energy stored, when more energy is stored in the water the shorter the reaction time. The problem that we had to answer was does temperature affect chemical reactions? My hypothesis was correct because the heated water had the shortest reaction time and the cold water had the longest reaction time.
Temperatures | Beginning | End | With Tablet | Time |
Cold | 6.7 C | 2.8 C | 3.2 C | 2 min 30 sec |
Room Temperature | 22.2 C | 23 C | 22.5 C | 34 sec |
Hot | 31.6 C | 50 C | 50 C | 21 sec |
The colder the water temperature gets the longer it takes for the tablet to dissolve than it does in warmer or hotter water. Different temperatures do affect chemical reactions because they can either speed up or slow down the process.
This graph shows the one with cold water and how the temperature just keeps dropping.
This graph shows the room temperature water and how it stay the same throughout the whole experiment.
This graph shows the heated water and something very interesting about this one is that the temperature kept fluctuating.
