The Phenomena accompanying Explosions and the Theories which have been proposed to Explain Them. The effect produced by an explosive is caused by the blow or impulse imparted through the rapid production from it of a large volume of highly heated gas. The explosive character of the change depends ? 1st. Upon the great change of state produced. 2d. Upon the time required for the change to take place. Both these causes operate to a greater or less extent in all explosive reactions. When both are fully exerted the most energetic chemical reaction, or, in other words, the most violent explosion takes place. The differences exhibited in explosions and by explosive bodies depend upon the different manner and proportions in which these causes act. Thus, nitro-glycerine is much more powerful and violent than gunpowder, because it generates a larger volume of gas in a shorter time, while fulminating mercury is not more powerful than gunpowder, because the quantity of gas given off, and the temperature of the reaction are less, but it is more violent, because the decomposition goes on more quickly. The kinds and quantity of gas given off in an explosive reaction depend upon the chemical composition ofthe explosive body and the character of the decomposition. The heat evolved during the reaction adds to the effect by increasing the tension (expanding the volume) of the gas formed. The heat given off in a reaction is an absolute quantity, the same whether the reaction goes on slowly or rapidly. But the exjrtosive effect will evidently greatly depend upon the rapidity of the formation and expansion of the gas. Thus, if an explosive undergoes the same change under all circumstances of firing, the force developed will always be the same, but the explosive effect wil...
