How does the volume of water effect how quickly sugar dissolves in it?

Extracts from this document...

Introduction

How does the volume of water effect how quickly sugar dissolves in it? In order to answer the above question I must conduct an experiment using the following equipment * Beaker - To Hold the eventual solution * Thermometer - To Track Temperature * Top Pan Balance -Measure amount of sugar * Spatula- Move Sugar from Bag to top pan balance * Sugar - This is the solute * Water - This is the solvent * Measuring Cylinder - Used to measure volume of water * Stopwatch - Used to take time readings of solute and solvent forming a solution. Measure out a volume of water using the measuring cylinder then pour the specified amount into a beaker Measure out a weight of sugar using top ...read more.

I will collect the results again and put them in a second table. I will plot a second graph before taking the average of the results 1 and 2. Taking the average of the results 1 and 2 will allow me to plot graph 3, which is the fair test graph. I predict that for the above experiment that the larger volume of the water will mean the sugar will dissolve quicker. I predict this will happen because the sugar dissolves into the gaps between the water molecules, if there is more water molecules this means there will be more gaps for the sugar to dissolve into meaning it will dissolve faster These are the first set of results I recorded Volume of Water (ml) ...read more.

This shows that the more water molecules there is the more gaps there is for the sugar to dissolve into. ...read more.
