Hot water is poured into a glass beaker and allowed to cool down for 5 minutes. Plan an experiment to investigate whether the rate of cooling of the hot water depends upon the initial temperature of the hot water. The rate of cooling of the water can be calculated using the equation: $$\[ \text { rate of cooling }=\frac{\text { decrease in temperature }}{\text { time taken }} . \]$$ You are provided with: - a supply of cold water - an electric kettle - a $$\(250 \mathrm{~cm}^{3}\)$$ glass beaker - a measuring cylinder. You may use any other common laboratory apparatus. In your plan, include: - any other apparatus needed - a brief description of the method, including what you will measure and how you will make sure your measurements are accurate - the variables you will control - a results table to record your measurements (you are not required to enter any readings in the table) - how you will process your results to reach a conclusion. You may include a labelled diagram.
