“…The enthalpies of combustion were measured with the rotating-bomb calorimeter formerly used at the National Physical Laboratory, Teddington, UK [21,22], with a tantalum-lined combustion bomb with an internal volume of 0.329 dm 3 . Water was added to the calorimeter from a weighted acrylic vessel, and for each experiment a correction to the energy equivalent was made for the deviation from 3965.0 g of the mass of water added.…”
