Problem
A laboratory thermometer is known to give the true value of the boiling point of water as 100.0∘C when perfectly calibrated. A student, however, records the boiling point as 99.2∘C.
(i) Calculate the absolute error in the student’s reading.
(ii) Calculate the relative error.
(iii) Find the percentage error and express it to two significant figures.
(iv) State, with a brief reason, whether the student’s measurement is accurate enough if the maximum permissible percentage error in the experiment is 1.0%.
