Abstract
THEORETICAL flame temperatures and explosion pressures calculated upon the basis of the quantum specific heats (which have been shown to be substantially correct1) are never reached in flames and explosions. Even when measurements of the actual flame temperatures and explosion pressures are postponed for such length of time as to make it certain that chemical combination is complete and full allowance is made for heat loss, there is still a defect of the measured temperatures and pressures below the calculated—a defect which remains constant in amount during the whole of this time. In short, in flames and explosions, definite ceiling temperatures and ceiling pressures are reached which fall short of the calculated temperatures and pressures.
