Towards the end of World War II with casualties high and morale low the U.S. military decided to unleash the most destructive weapon the world has ever seen. The atomic bomb was a newly developed weapon able of causing destruction beyond any weapon before it. Two of these bombs were dropped on Japanese cities. The first on Hiroshima on August 6th‚ 1945 and the second on Nagasaki on August 9th‚ 1945. The immediate devastation of the atomic bombs on Hiroshima and Nagasaki was the only display of power

Three things are usually required for a chemical explosion: a chemical reaction that occurs very rapidly‚ a large increase in gas pressure‚ and a confined-reaction vessel in which the pressure of the gaseous products can increase to a point that the gases break violently out of the container. In this chemistry and physics science fair project‚ you will use the combustion of ethanol to provide energy for a small explosion. The chemical equation that describes the combustion of ethanol is shown below

Arms control Arms control is a term for restrictions upon the development‚ production‚ stockpiling‚ proliferation‚ and usage of weapons‚ especially weapons of mass destruction.[1] Arms control is typically exercised through the use of diplomacy which seeks to impose such limitations upon consenting participants through international treaties and agreements‚ although it may also comprise efforts by a nation or group of nations to enforce limitations upon a non-consenting country.

Effects of thermal runaway A runaway exothermic reaction can have a range of results from the boiling over of the reaction mass‚ to large increases in temperature and pressure that lead to an explosion. Such violence can cause blast and missile damage. If flammable materials are released‚ fire or a secondary explosion may result. Hot liquors and toxic materials may contaminate the workplace or generate a toxic cloud that may spread off-site. There can be serious risk of injuries‚ even death‚ to plant

way that winds circulated dust through the atmosphere and how large amounts of dust‚ such as that from volcanic explosions‚ might affect Earth’s climate. His study of Earth’s atmosphere led him to formulate the idea of nuclear winter with American scientists Paul and Anne Ehrlich in the 1980s. Sagan and the Ehrlichs theorized that the dust and ash thrown into the atmosphere by the explosions of a nuclear war and the ensuing fires might be so thick and widespread that it would block the Sun’s light for
