Using a thermometer that has a bubble inside (this causes all readings to be at 2.0°C too high), Al obtained the temperature of a solution to be 45.3°C. Al then heated the solution and using the same thermometer, the thermometer is 56.7°C. Al recorded the temperature change to be 11.4°C. Is this temperature change accurate? Why or why not?

The temperature change obtained by Al is accurate

Data obtained from the question

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:

How to determine the accurate temperature change

  • Faut of thermometer = 2 °C high
  • Initial temperature (T₁) = 45.3 - 2 = 43.3 °C
  • Final temperature (T₂) = 56.7 - 2 = 54.7 °C
  • Change in temperature (ΔT) = ?

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
