Time taken to heat water to 50C A kettle is used to increase the temperature of 0.25 L of water by 50C, and the time taken for the temperature to change is measured three times. The same kettle is used to increase the temperature of 0.45 L of water by 50C. Again, three measurements are made. Time (+/-0.2 s) Volume (+/-0.01 L) trial 1 trial 2 trial 3 1. 0.25 15.5 15.2 15.9 2. 0.45 45.1 44.9 45.4 The measured results are shown in the table. The known time for #1 is 15.4 s and for #2 is 46.2 s. Compare the precision and accuracy of each set of results. Calculations: Precision: Accuracy:
