TNT can release its energy very rapidly. This means its rate of transfer from energy into heat is very high. This heat that is released when the TNT explodes causes it to become a gas that expands very suddenly into the space that the objects around it occupy, pushing them out of the way and creating an explosion. TNT has remarkable power (rate of energy transfer). In addition, as soon as a part of the TNT starts to explode, the rest of it is triggered and also explodes, within one millionth of a second. These characteristics of TNT make it a highly effective explosive, despite its little relative energy per gram.
