When
I think about explosions, I do not know the science behind them I just know it
is violent, involves chemicals in some way, and can be quite intense. On a
website called Chemistry Explained, I now understand a little more on
the science behind explosions. An explosions is a sudden, violent change of
potential energy to work that is transferred to its surroundings in the form of a
rapid movement with rise in pressure which causes a blast wave or shock wave.
Knowing this helped me understand the lesson we just went over in chemistry
about potential energy, work, and surroundings. There are three types of
explosions; nuclear, chemical, and physical. So what’s the difference?
According to Chemistry Explained, nuclear explosions often are caused by fusion or
fission reactions. With the fusion reaction the nuclei of two small atoms combine
to form a single larger atom, because the mass of the products of the reaction
is less than the mass of the reactants the difference in mass is converted to
energy. With fission reactions, the splitting of the atom caused by
neutrons. Chemical explosions are exothermic where decomposition or
composition where energy is converted to work. Physical explosion deals with
high pressure like when a tire or a balloon has too much hair in it then POP!!
That’s a physical explosion. You can learn more at:
