The temperature change obtained by Al is accurate
From the question, we were told that the thermometer is faulty, given a reading that is 2.0 °C too high.
Al obtained a temperature change of 11.4 °C.
This value (11.4 °C.) is consider accurate because twhen we subtract 2 from both the initial and final temperature, the change in temperature obtained will still be the same. This is illustrated below:
ΔT = T₂ - T₁
ΔT = 54.7 - 43.3
ΔT = 11.4°C
Thus, we can see that the result obtained is still 11.4°C. Therefore, the temperature change obtained by Al is accurate
