Introduction
The below are the possible factors that might affect how quickly a sugar cube dissolves in water temperature of water/liquid water being shaken water being stirred the sugar lump being loose amount of sugar in the cube
In this experiment, I will be investigating if the change in water temperature (independent variable) would affect the time it takes for sugar to dissolve (dependent variable).
Aim
The aim of this experiment is to find out if the water’s temperature would affect the time it takes for sugar to dissolve. To do that, we would investigate the time it takes for the a sugar cube to become flat in the bottom of a beaker.
Hypothesis
I think that the warmer the water is, the faster the sugar …show more content…
Same amount of water Using the same amount of water because putting 2 ice cubes into 1 liter of water and putting 2 ice cubes into 150ml would result in a different temperature because there would be less ice to go around.
4. The same person We should use the same person for dropping the sugar and timing to minimize reaction time and to avoid dropping the sugar cube into the water accidentally

Conclusion
Based on the results from the experiment, the temperature of water does affect the time it takes for sugar to dissolve, the line of best fit also shows the same results. The results I got showed that the warmer the water, the faster sugar dissolves. The results mostly proved my hypothesis correct, which is the warmer the water the quicker sugar will dissolve in it because there would be more space between each particle.
