How does temperature affect the dissolving rate of a sugar cube?

Extracts from this document...

Introduction

´╗┐Intro: The question being tested in our experiment is ?How does temeperature affect the dissolving rate of a sugar cube?? I performed a similar experimentlast year, except in that experiment there were only three temperatures in which the sugar cube was to be put into. There was 10, 50 , and 100 degree water divided into three beakers. I predict that the results to this experiment will be similar to the ones last year. Meaning that the otter the water temperature the faster the sugar cube will disolve or in other words disperse or dissapear. ...read more.

Materials: -Sugar cubes -Hot plate -Water -1,000 mL beaker -Thermometer -Ice cubes -Goggles Methods: The first step would be to fill a 1,000 mL beaker with water up to 300mL. The next step would be to bring the water to appropriate temperautre by heating it on a hot plate or adding ice. The next thing to do would be to add the sugar cube to the water and observe the sugar cube until it dissolves. The final step would be to record the amount of time it took the sugar cube to dissolve. ...read more.

In some trials we couldnt get the temperature to be exact so it was a little off. Another factor was when ice was added to the beaker it also added onto the amount of water so it was over 300mL of water. Overall it was easy to understand that the warmer the temperature the faster the sugar cube will dissolve. ...read more.
