And here again, after a small burden of examination of electromagnetism, several practices and stuff. Today we will see a small demonstration of what a nuclear chain reaction.
As we know, a heavy, unstable atom can fission spontaneously breaking into several pieces, some of these neutrons, which can help other atoms to fission, which releases more neutrons, more atoms to fission .. . The process releases large amounts of energy, which is what we use in our nuclear power plants to produce electricity. Of course, This energy production is controlled so as not to release such amount in such a short space of time can be dangerous.
But what happens if this reaction is controlled. It is customary that if there is a sufficient amount of fissile material, heavily exploited. If there is enough material to explode, the heat released by the reaction is so large that it can melt almost anything it touches.
This level of "what you see from the outside" but sometimes it's a bit difficult to get an idea of \u200b\u200bwhat happens at the atomic level. Okay, we know that an atom fissions and blablabla ... How fast? This is what we will see in the next video.
