Why do nuclear bombs make such a loud "pop"? The Fuel value of hydrogen is 142 x 10 3 J g -1 If all matter were converted into energy E = 1x10 -3 kg * (3x10 8 m/s) 2 E = 9x10 13 kg m 2 s -2 E = 9x10 13 J In other words, we can get out about 9 orders of magnitude greater energy if the hydrogen is converted directly into energy, rather than combusting it. Nuclear fission and fusion reactions convert a fraction of their matter into energy. The bomb that was dropped on Hiroshima contained about 15 kg of the 235 Uranium isotope, a fissionable material. The actual amount of mass that was converted into energy is estimated at about 1 kg (releasing around 1 x 10 17 J of energy in a split second). The estimated temperature at the moment of detonation is estimated to have been around 5 million degrees. In addition to the sun-like heat, much of the damage

Unformatted text preview: was due to the pressure wave that was produced. The Uncertainty Principle For a relatively large solid object, like a bowling ball, we can determine its position and velocity at any given moment with a high degree of accuracy. However, if an object (like an electron) has wave-like properties then how can we accurately define its' position? Werner Heisenberg (1901-1976) concluded that due to the dual nature of matter (both particle and wavelike properties) it is impossible to simultaneously know both the position and momentum of an object as small as an electron. Thus, it is not appropriate to imagine the electrons as moving in well-defined circular orbits about the nucleus....
