Aim:
The aim of this investigation is to determine the effect of water temperature on the time it takes for an aspirin tablet to dissolve.
Hypothesis:
The boiling water will have the quickest time to dissolve the aspirin tablet. This is because its molecules have more energy and are vibrating more rapidly than the cold water. Cold tap water will have the slowest time to dissolve the aspirin tablet because it has the least kinetic energy. Why?

I hypothesized that the boiling water will have the quickest time to dissolve the aspirin tablet. This is because its molecules have more energy and are vibrating more rapidly than the cold water. I also hypothesized that the cold tap water will have the slowest time to dissolve the aspirin tablet because it has the least kinetic energy.
The investigation I conducted supports my hypothesis. In my first 13°C test the average of the results was 73.72 seconds. In the second 25°C test the average of the results was 46.25 seconds. In my third 60°C test the average of the results was 34.03 seconds. In my fourth and final 100°C test the average was 23.47 seconds. The results indicate that as you raise the temperature of water the dissolving time of aspirin decreases. Because of the results it’s clear to see that the 100°C water is the best water temperature to dissolve the aspirin in.
Each test was done three times for each data point to ensure reliable and accurate results. My data set could have been affected by experimental errors such as instrumental errors and parallax error. My method was fair and was suited to investigate the effect of water temperature on the dissolving time of aspirin. The results were never more than 5 seconds apart which is an acceptable margin of
