Exactly 1.5 g of a fuel burns under conditions of constant pressure and then, in a
second experiment, under conditions of constant volume. in one case (not
necessarily the first), the reaction produces 25.9 kj of heat and in the other it
produces 23.3 kj of heat. which measurement corresponds to the conditions of
constant pressure? justify your answer.
