2 A student measures the change in temperature of some water when it is heated for 10 seconds.
The student’s results are:

Final temperature = (96.1 ± 0.2) °C
What is the average rate of change in temperature of the water together with its associated
uncertainty?
A (4.27 ± 0.02) °C s–1
B (4.27 ± 0.04) °C s–1
C (4.27 ± 0.2) °C s–1
D (4.27 ± 0.4) °C s–1
