Water is heated from room temperature to its boiling temperature in a glass beaker. Plan an experiment to investigate if the time taken for the water to reach its boiling temperature depends on the diameter of the water surface exposed to the air. You are provided with: • a supply of cold water • a set of glass beakers of different sizes • a Bunsen burner, tripod and gauze • a measuring cylinder. You may use any other common laboratory apparatus. You are not required to do this investigation. 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 draw a conclusion. You may include a labelled diagram if you wish.
