Does The Temperature Of 75ml Of Water Affect How Quickly A Mixture Of Sugar Dissolves
How does the temperature of 75mls of water affect how quickly one teaspoon of sugar dissolves?
Aims and Objectives
The aim of this scientific enquiry is to determine if and how the temperature of 75mls of water affects the speed in which sugar can dissolve in. The objective is to use three different independent variable temperatures of water. Then record three dependent variables of time in which the sugar dissolves in the different temperatures of water being used. One being cold, which in this enquiry is an average temperature of twenty four degrees, Warm which is an average temperature of forty five degrees and hot water which is an average temperature of eighty two degrees. The results are then recorded and observed to see if any patterns have occurred.

Valanides (2000) goes on to say that occasionally the components will have a small effect on each other, with each of the components remaining visible. In other situations mixing materials can achieve dramatic permanent changes to the materials, dissolving lies somewhere between these two examples. Hesse (1992) states that the most universal example of dissolving involves a solid and a liquid, usually water. When a solid called a solute is mixed with a liquid called a solvent, the solute particles breakdown and spread them selves out to be closer to the solvent particles. This mixture is then called a solution. If the solute is coloured it will be easy to see a visible change, however if the solute was colourless, then the solution may look like the original solvent. The occurrence of dissolving can be seen in many every day activates, such as putting sugar into tea or coffee or the ocean dissolving away your sand
