Problem
A copper calorimeter was used to determine the enthalpy of combustion of butan-1-ol. The experimental value obtained was −2100±200kJ mol−1, and the data booklet value is −2676kJ mol−1.
Which of the following accounts for the difference between the two values?
(I) Random measurement errors
(II) Incomplete combustion
(III) Heat loss to the surroundings
(1) I and II only
(2) I and III only
(3) II and III only
(4) I, II and III
